sepolicy: Start slim Common sepolicy

Rather than having to maintain out of tree changes, it is often
easier to maintain a hiearchy of changes, starting with the vendors
common config file. From there, inheriting products can pick up a base
and start to add or remove certain bits from it, making use of the
BOARD_SEPOLICY_* functions documented in external/sepolicy/README.

TODO: our gapps have another sign key...we need to add as well
