This fixes a regression introduced in 4b06383.
[dezgeg squashed in to fit the changes introduced in "db: Use more
conventional outputs, also split bin"]
* Remove explicit setting of PERL5LIB.
* Use the generic Perl builder for the BerkeleyDB and XML::Parser
modules.
* Prefix all names of Perl modules with `perl-' (in the generic Perl
builder).

* Make builders unexecutable by removing the hash-bang line and
execute permission.
* Convert calls to `derivation' to `mkDerivation'.
* Remove `system' and `stdenv' attributes from calls to
`mkDerivation'. These transformations were all done automatically,
so it is quite possible I broke stuff.
* Put the `mkDerivation' function in stdenv/generic.
