Use archive_entry_set_perm instead of archive_entry_set_mode
This patch fixes FS#12148 ('unstable' regular file).
I also changed the other archive_entry_set_mode usage in add.c to
archive_entry_set_perm.
Since I cannot find any relevant info in libarchive manual, I quote
Tim Kientzle (the author of libarchive) here, and I say thank you for
his help.

This is the problem in libalpm/util.c:
323 if(S_ISREG(st->st_mode)) {
324 archive_entry_set_mode(entry, 0644);
325 } else if(S_ISDIR(st->st_mode)) {
326 archive_entry_set_mode(entry, 0755);
327 }
Your example unstable.db.tar.gz is not empty. It has
one entry in it, called "./". That entry is marked
as a directory. But, when you call archive_entry_set_mode(),
you are changing the file type! archive_read_extract()
then creates the file /var/unstable as you requested.
(archive_read_extract() will replace an empty directory
with a file.)
You should either set the mode value correctly:
323 if(S_ISREG(st->st_mode)) {
324 archive_entry_set_mode(entry, IFREG | 0644);
325 } else if(S_ISDIR(st->st_mode)) {
326 archive_entry_set_mode(entry, IFDIR | 0755);
327 }
Or use archive_entry_set_perm(), which does not change
the file type:
323 if(S_ISREG(st->st_mode)) {
324 archive_entry_set_perm(entry, 0644);
325 } else if(S_ISDIR(st->st_mode)) {
326 archive_entry_set_perm(entry, 0755);
327 }
