hob: don't set PARALLEL_MAKE and BB_NUMBER_THREADS based on cpu count

This was actually broken with recent changes as the values were never
persisted to a file (meaning they were unset on the server at reparse
despite the UI indicating they were set).

However, I've chosen to remove the 'feature' as pegging a users CPU without
them asking to use high thread counts seems a little offensive.
