bacman: use globbing to get local package db path
The original code- pkg_dir="$(echo $pac_db/$pkg_name-[0-9]*)" is problematic in several ways: - $pac_db and $pkg_name should be quoted, obviously. - It assumes pkgver always starts with an integer, while in fact it just can't contain ':' and '-'. Counterexample: the code breaks on lshw B.02.15-1. - It assumes there are no more than one directory matching the pattern. While this should be the case if everything works perfectly, it certainly relies on external conditions. Counterexample: if the local db contains two packages named foo and foo-3g, even if everything else is perfect, the code will match two directories. Don't make assumptions, use what is known.
