moveconfig: Allow regex matches when finding combinations

Browse Source 
It is useful to be able to search for CONFIG options that match a regex,
such as this, which lists boards which define SPL_FIT_GENERATOR and
anything not starting with ROCKCHIP:

   ./tools/moveconfig.py -f SPL_FIT_GENERATOR ~ROCKCHIP.*

Add support for this.
