make: extract compile tags

Add a new COMPILE_TAGS environment variable that includes all the basic
set of tags that lit requires in order for compilation to succeed. Let
LND_RELEASE_TAGS then extend these flags.

This will let us expand the testing_flags.mk file later without needing
to use the LND_RELEASE_TAGS variable there.
