Route all candidate packages via find_pkg_match().

Previously any package that wasn't considered a glob was passed right
though, but due to some later exact_pkgfmt checks could result in
questionable results.

For example, given the following available packages:

  tex-pst-2dplot-1.5   PSTricks package for drawing 2D curves
  tex-pst-2dplot-doc-1.5  Documentation for tex-pst-2dplot

Running "pkgin install tex-pst-2d" would result in an install attempt
for tex-pst-2dplot-doc, due to "-2" being handled as a version match,
which differs from regular package match behaviour.

Passing all package requests through find_pkg_match() first ensures we
now get the correct:

  tex-pst-2d is not available in the repository

even if it is slightly more expensive.
