Fix for FS 6404 and functionalize some cachedir handling stuff

In order to best resolve bug 6404, move some cachedir handling stuff out of
sync.c and into util.c and create two new functions: filecache_find and
filecache_setup. sync.c was rewritten to use these, and alpm_fetch_pkgurl
now also uses these routines.
