Fix segfault when uninstalling broken backed-up symlink
Issue FS#24230. If a symlink is broken and included in the removal process of a package, we blew up and segfaulted due to alpm_compute_md5sum() returning NULL and then performing a strcmp() operation. Signed-off-by: Dan McGee <dan@archlinux.org>
