KVM: selftests: Include lib.mk before consuming $(CC)
Include lib.mk before consuming $(CC) and document that lib.mk overwrites
$(CC) unless make was invoked with -e or $(CC) was specified after make
(which makes the environment override the Makefile). Including lib.mk
after using it for probing, e.g. for -no-pie, can lead to weirdness.
