Adam Joseph 42815b4a0c treewide: systemdSupport: use lib.meta.availableOn
Many packages have some kind of flag indicating whether or not to build with
systemd support.  Most of these default to `stdenv.isLinux`, but systemd does
not build on (and is marked `broken` for) `isStatic`.  Only a few packages have
the needed `&& !isStatic` in the default value for their parameter.

This commit moves the logic for the default value of these flags into
`systemd.meta.{platforms,badPlatforms}` and evaluates those conditions using
`lib.meta.availableOn`.

This provides three benefits:

1. The default values are set correctly (i.e. including `&& isStatic`)

2. The default values are set consistently

3. The way is paved for any future non-Linux systemd platforms (FreeBSD is
   reported to have experimental systemd support)
