Change fontawesome-fonts requires to match fontawesome 4.x

fontawesome 6.x is not entirely compatible with 4.x version but in
Fedora the change was made to make 4.x bits FreeIPA depends on to be
forward-ported to 6.x build. This also allows to have common dependency
for all versions.

This patch switches to the common dependency using 'fonts(fontawesome)'.
This works on all Fedora and RHEL versions.
