cleanup(catalyst): Updates for catalystrc

Remove the catalystrc code that updated /etc/locale.gen, it wasn't
generally effective since catalyst installs things without
CONFIG_PROTECT and therefore locale.gen always got overwritten just
before it was going to be used. Add --load-average to MAKEOPTS so
builds better manage their parallelism when multiple independent jobs
are compiling code. Disable some locking to speed up builds that use
lots of binary packages.
