Add a "Kernel selftests" sub-menu with one entry per selftests directory

make, so the selected ones build in parallel. Selftests whose Makefile
does not use KHDR_INCLUDES still build against the C library's copy of
the UAPI headers.
The selftests do not track header dependencies, so a selftest is built
again from scratch when its own directory, a header or makefile any
selftest may share, or a kernel source it includes directly (the vDSO
test includes the architecture's vDSO code) is newer than its last
build.
Is there a way you can fold in kselftest_deps.sh run into this
so users know why some tests didn't build. Also we want to make
sure kselftest build doesn't fail if a test fails to build to
keep the current kselftest build behavior.
Sure. In the next version a selftest that fails to build prints a warning and
the build carries on, as with kselftest-all. FORCE_TARGETS=1 makes it fatal, as
it does for kselftest-all, for CI that wants that.
