opkg-build: Add support for explicit pigz

From: Mike Crowe <[email protected]>

oe-core has stopped[1] installing pigz as gzip. This means that in order to persuade opkg-build to use pigz it must be specified explicitly. Let's teach opkg-build to deal with being passed pigz as a compressor. We can't combine the check for whether -T is required because opkg-build calls both $compressor and gzip explicitly.
