treewide: clean up recipe checks in OBMC_MACHINE_FEATURES

OBMC_MACHINE_FEATURES is a variable that probably shouldn't even exist
as all it does is provide a level of indirection to the real
MACHINE_FEATURES (in phosphor-base.inc, OBMC_ is added to the base).
There are a few recipes that have developed checks against
OBMC_MACHINE_FEATURES for enabling recipe-level features when they
should be checking the standard MACHINE_FEATURES variable.  Clean up
this recipe-level indirection.
