makefiles/tools/serial: ensure PORT is set and fail early.

Browse Source 
By ensuring the PORT auto-detection worked, we can give meaningful
error messages and fail earlier.

This uses ensure_value from makefiles/utils/checks.mk. An include was
added to Makefile.include to make this fuction available to all other
makefiles.
