Subject: [PATCH 14/21] vfio: selftests: Add Makefile support for TEST_GEN_PROGS_EXTENDED

Add Makefile support for TEST_GEN_PROGS_EXTENDED targets. These tests
are not run by default.

TEST_GEN_PROGS_EXTENDED will be used for Live Update selftests in
subsequent commits. These selftests must be run manually because they
require the user/runner to perform additional actions, such as kexec,
during the test.
