[RFC PATCH 4/9] make_fit_atf.py: produce working binaries by default

[Petr Štetiar]

At this moment unusable binaries are produced if bl31.elf file is
missing in order to allow passing of various CI tests. This intention of
broken binaries has to be now explicitly confirmed via new
BUILDBOT_BROKEN_BINARIES config option, so usable binaries are produced
by default from now on.
