Subject: Alternatives: avoid explicit paths to update-alternatives


Using installation path macros in file dependencies is disallowed by
commit 35d89f0f3ff118359f1fef1c328570a944e0ddf8 ("Recommend avoiding
macros in file depenencies") and breaks flatpak builds when the
dependency is in the runtime.  Furthermore, with the bin-sbin merge,
using %_bindir is only compatible with F42+.
