Fix line_offset not being reset in _alpm_archive_fgets()
This is a rather serious data corruption issue that luckily manifested
itself today in a noticable way. A package in testing had replaces
entries read in as ["%RE pkgname", "%RE"] which was clearly wrong. This
happens when we hit the end of an archive block, do not have a newline,
and have to continue reading from the next block to complete the line.
