In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

Commit fe1151218c ("chiaki: cleanup package") replaced mkDerivation
with stdenv mkDerivation, which is wrong for QT5 applications and
results in the following error on start:
qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""
qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
also see [1] in the manual. Fix the package by using mkDerivation again.

Darwin requires qtmacextra in the buildInputs, otherwise compilation
fails with:

Chiaki supports the touchpad on DualShock4 controllers when they are
connected via USB and requires libevdev & udev for this. Add both
libraries if chiaki is to be built for a Linux host.
Also switch the upstream repository from github to git.sr.ht, since the
project has been moved to sourcehut.

After making `ffmpeg` point to the latest `ffmpeg_4`, all packages that
used `ffmpeg` without requiring a specific version now use ffmpeg_3
explicitly so they shouldn't change.
