util.c : fix segfault when the cachedir isn't usable.

Browse Source 
For example, if the cachedir is a broken symlink or a non writable
directory, pacman fallbacks to /tmp/. Just before doing that, it freed the
handle->cachedirs list twice !
once in _alpm_filecache_setup, and once in alpm_option_set_cachedirs. So the
first one was removed.

Fixes FS#9186.
