Fix build with %_sbindir==%_bindir, add compat sbin Provides
    
    https://fedoraproject.org/wiki/Changes/Unify_bin_and_sbin
    
    If %_bindir==%_sbindir, build would fail because both locations are the same
    and we cannot create the symlink.
    
    Also add compat Provides so that packages requiring the old paths in /usr/sbin
    continue to build (openssl). We rely on the filesystem to create the sbin
    symlinks for us, so add an appropriate dependency so that the new Provides is
    not a lie.
