alpm_unpack : change prefix handling to workaround FS#12148.

Instead of appending the prefix to each entry name, we can chdir to the
prefix before extracting, and restoring when it is done.
This seems to work better with the strange and special case of FS#12148
where an archive contained the "./" entry.
