[Nico Huber (Code Review)]

Hello build bot (Jenkins), Angel Pons,

Makefile: Add macro to disable unsupported programmers

`mark_unsupported` disables all programmers passed as arguments and
adds them to the UNSUPPORTED_FEATURES list. It's conveniently used
with our dependency lists, e.g.

$(call mark_unsupported,$(NEEDS_LIBUSB1) $(NEEDS_LIBFTDI))
