These packages were duplicated, and often weren't being updated in sync.
The only difference between them was the lack of pkg-config in
libraspberrypi, which is easily fixable.
This derivation uses wrapPython to wrap some "test scripts" that are
shipped in the "test" output.
As these test scripts require gobject-introspection, which doesn't
cross-compile at all, let's only patch and ship them when not
cross-compiling.
The current `fix-dbus-tests.patch` uses automake and pkgconfig to figure
out the path of `dbus-daemon`. This fails when cross-compiling, as
tests aren't run (and `checkInputs`) not available.
Instead of doing this, we can simply teach the tests to pick up
dbus-daemon from $PATH. This was also sent upstream in
https://lists.01.org/hyperkitty/list/ell@lists.01.org/thread/SQEZAIS2LZXSXGTXOW3GTAM5ZPXRLTN4/.
Switch from wykurz to lpechacek fork, so we can use Python 3 instead of
Python 2. However, Python 2 should still works.
Also, fix this issue since it is easy:

This was pushed to master without a PR and broke cross compilation of a
small cross-NixOS:
```
configure: error: in `/build/alsa-firmware-1.2.4':
configure: error: C compiler cannot create executables
See `config.log' for more details
```
Let's re-roll this in a PR.
This reverts commit 72f71e9071.
The shell script coming with the vendor-provided udev rule simply
starts dlm.service (and sets up some symlinks), and stops dlm.service if
that was the last card plugged in.
On NixOS, some of the cat/grep/sed commands are not available, causing
the script to fail.
Turns out, the symlinks aren't needed at all. Archlinux ships their own
script
(https://aur.archlinux.org/cgit/aur.git/plain/udev.sh?h=displaylink),
which only starts and stops dlm.service, depending on whether there's
cards left or not.
We can further optimize this by simply starting dlm.service on the first
card, and not stopping it at all. Considering dlm won't get stopped if
one of multiple cards is unplugged, it seems to handle disconnects.
