vboot: Allow enabling unit test console output

By passing TEST_PRINT=1 to make, VBOOT_DEBUG symbol will be defined and
hence cause the stub vb2ex_printf() to print to stderr. Note that
DEBUG=1 will also imply VBOOT_DEBUG as before.

TEST=make clean && TEST_PRINT=0 make run2tests
TEST=make clean && TEST_PRINT=1 make run2tests
