- Upgraded dependencies
- dependencies script upgraded to take into account new WORKSPACE
rules
- Tests now depends on the `distdir`
Runtime bazel now also depends on the `distdir` setting which appears
in the global configuration file. This increases the bazel closure
size by 85 MO for stuffs which can normally be downloaded at runtime
by bazel. However, any invocation of `buildBazelPackage` (such as in
`bazel-watcher`) may fail in nix sandbox if theses files are not
available at runtime.
If this overhead is too important, we may later evolve to a finer
grained solution, where buildBazelPackage declares the list of
necessary dependencies.
The bazel build patches paths like `/usr/bin/install_name_tool` to refer
to `${cctools}/bin/install_name_tool` instead. If the corresponding
runtime dependency is not denoted, then darwin users can encounter "file
not found" errors, e.g. when they fetch bazel from a binary cache and
don't have `cctools` in their own nix store.
There ver very many conflicts, basically all due to
name -> pname+version. Fortunately, almost everything was auto-resolved
by kdiff3, and for now I just fixed up a couple evaluation problems,
as verified by the tarball job. There might be some fallback to these
conflicts, but I believe it should be minimal.

The shebang in the python stub template was incorrectly patched to
```
<store-path>/bin/env python
```
instead of
```
<store-path>/bin/python
```
The reason was that `patchShebangs` was called with `--replace` which is
an unknown argument.
```
patching script interpreter paths in src/main/java/com/google/devtools/build/lib/bazel/rules/python/python_stub_template.txt --replace /usr/bin/env python /nix/store/w7gsq8v86hni4ynaqgwwlnlny115ylng-python3-3.7.4/bin/python
find: unknown predicate `--replace'
```
Using `substituteInPlace` instead resolves that issue.
The wrong shebang caused failures of `py_binary` targets due to `python`
not being in `PATH` in certain circumstances.
Turns out markers are non-deterministic after all and even our patching still
doesn't solve this problem completely. For example (tensorflow deps, this is a
complete diff so actual dependencies don't differ):

And here's an example of differences:

cat result-b/@bazel_skylib.marker

$MANAGED
Instead of trying to patch these markers further we now completely clear them.
Nix hacks for ignoring markers are restored and expanded so that we don't even
attempt to parse the marker.
Also drop preInstall cleanup for dependencies. The reason is while it's more
thorough than default cleanup in buildBazelPackage if such a problem happens we
should fix buildBazelPackage instead. Perhaps even move this (awesome!) snippet
there but it's very slow-running so we'd rather attempt to fix it in other
ways.
Anyway after an update at least .deps build, checked with `nix-build -A --check`.
