Subject: [PATCH 1/3] tools: testing: Allow importing arch headers in shared.mk

There is an arch/ tree under tools. This contains some useful stuff, to
make that available, import the necessary Make helper file and then add
it to the -I flags.

There still aren't that many headers so also just smush all of them into
SHARED_DEPS instead of starting to do any header dependency hocus pocus.
