tools: testing: support EXTRA_CFLAGS in shared.mk

Browse Source 
This allows the user to set cflags when building tests that use this
shared build infrastructure.

For example, it enables building with -Werror so that patch-check scripts
will fail:

	make -C tools/testing/vma -j EXTRA_CFLAGS=-Werror
