pmb.build: use pigz instead of gzip (MR 2252)

Browse source 
This is multithreaded, and by consequence much much faster than default
gzip. Since we switched to running gzip from the native chroot we also
changed from running it in the fastest mode, now we're running it with
-9 it can be pretty slow on any kind of mobile hardware.
