Subject: common: implement find_cached_package

This function (currently) searches through $PWD and $PKGDEST looking
for a tarball matching the requested package name, architecture, and
pkgver. If found, it writes the full path to the located package to
stdout and returns 0, else 1. If more than 1 match is found, it's
treated as an error and the user will need to figure out what to do.

Use this in checkpkg and commitpkg, which previously implemented their
own less complete logic, to locate the build artifacts they rely on.

Subject: find_cached_package: avoid adding duplicates

If PKGDEST is set when makepkg was run, the package will be present in
find_cached_package's search path by default, causing an error.

This also fixes a display bug which causes no output to be shown when
multiple packages are found.

Fixes FS#37626.
