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.
Signed-off-by: Dave Reisner <dreisner@archlinux.org> --- This fixes a regression I caused in 9c85d116f042 which didn't consider finding the package in PKGDEST. I took the heavy handed approach and wrote a generic function to find cached packages since we do this in both checkpkg and commitpkg (and maybe some day elsewhere). Neither of the existing solutions are particularly thorough.
Replying to myself...

Need to print an error here because we don't return enough to the caller to let them differentiate between no results and multiple results.
