repo-add: use bsdtar optimization for better performance
When unzipping packages and the database archives, we don't need to look
through the entire archive to do what we need to do. For packages, .PKGINFO
should only be found once and should be the first file in the package. For
the database check, we only really need to look for one desc file.
The bsdtar -q option is very similar to the GNU tar --occurrence=1 option.
Example of speedup:
$ time repo-add junkdb.db.tar.gz *.pkg.tar.gz >/dev/null
real 0m16.159s
user 0m14.836s
sys 0m2.277s
$ time ./scripts/repo-add junkdb.db.tar.gz *.pkg.tar.gz >/dev/null
real 0m4.949s
user 0m3.730s
sys 0m2.093s
