fontcache: allow to pass extra parameters and environment to fc-cache
* this can be useful for passing extra parameters, pass -v by default to see what's going on in do_rootfs * we need to use this for extra parameter we implemented in fontconfig: --ignore-mtime always use cache file regardless of font directory mtime because the checksum of fontcache generated in do_rootfs doesn't match with /usr/share/fonts directory as seen on target device causing fontconfig to re-create the cache when fontconfig is used for first time or worse create new cache in every user's home directory when /usr/ filesystem is read only and cache cannot be updated. Running FC_DEBUG=16 fc-cache -v on such device shows: FcCacheTimeValid dir "/usr/share/fonts" cache checksum 1441207803 dir checksum 1441206149 * my guess is that the checksum is different, because pseudo (which is unloaded when running qemuwrapper) or because some influence of running the rootfs under qemu.
