intelvbttool: Add Makefile

Add minimal Makefile based on cbmem’s Makefile.

The make target `junit.xml` is removed as this is handled differently
since commit de9adebb (Add junit.xml code to top Makefile.inc instead of
utils).

Also the `junit.xml` is removed in the make target `clean`.

Additionally, the make target `distclean` is added, as the current
junit.xml code in the top `Makefile.inc` requires that.
