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.
