I haven't tried such a cache.  But I did change something in
FcDirCacheHasCurrentArch so that it'll properly detect changes in MAGIC

It's totally valid to have fontconfig 2.2 at the same time on some
machines that mount the same filesystem, so I guess that we should not
remove fonts.cache-1 files.
