3.4 branch detects support for getrandom() call during configure-time,
which gets picked up since glibc-2.25, and consequently it will fail
with older kernels during rutime.
Since systemd version 232 the install subcommand of bootctl opens the
loader.conf with fopen() modes "wxe", where the "e" stands for
exclusive, so the call will fail if the file exists.
For installing the boot loader just once this is fine, but if we're
using NIXOS_INSTALL_BOOTLOADER on a systemd where the bootloader is
already present this will fail.
Exactly this is done within the simpleUefiGummiboot installer test,
where nixos-install is called twice and thus the bootloader is also
installed twice, resulting in an error during the fopen call:
Failed to open loader.conf for writing: File exists
Removing the file prior to calling bootctl should fix this.
I've tested this using the installer.simpleUefiGummiboot test and it now
succeeds.

This leads to the following error when trying to install a new machine
where the machine ID wasn't yet initialized during boot:
Failed to get machine did: No such file or directory
In addition this was also detected by the simpleUefiGummiboot installer
test.
So let's generate a fallback machine ID by using
systemd-machine-id-setup before actually running bootctl.
Tested this by running the installer.simpleUefiGummiboot test, it still
fails but not because of the machine ID.

Add link to "Configuration" chapter from "Changing the Configuration" section.
Also, fix grammar error.
(cherry picked from commit a585f987fa32f2e81b3f273291971151c25f98b7)
So this was suggested as [long ago as October, 2015](https://github.com/NixOS/nixpkgs/issues/10376#issuecomment-147734898).
Despite being fairly ignorant of the nix Python support, I decided
that I really wanted this; this change brings in what I believe are
the necessary components---I have, at least, successfully run `beet
replaygain` and `beet bpd`---but it may not do it in the best way; I'm
happy to consider input on that front.
I can at least state that all three changes are necessary---leave any
one of them out and gstreamer support doesn't work.
