Set errno to 0 at the start of _alpm_open_archive as it is not set when
archive_read_open_fd fails. This can result in _alpm_pkg_load_internal
thinking errno == ENOENT and setting the wrong pm_errno. e.g.
Before:
> testpkg pacman-4.0.1-4-i686.pkg.tar.gz.sig
error: could not open file pacman-4.0.1-4-i686.pkg.tar.gz.sig: Unrecognized archive format
Cannot find the given file.
After:
> testpkg pacman-4.0.1-4-i686.pkg.tar.gz.sig
error: could not open file pacman-4.0.1-4-i686.pkg.tar.gz.sig: Unrecognized archive format
Cannot open the given file.
