kernel-selftest: Update to allow for turning on all tests

In testing adding in more kernel-selftests there were a number of issues
that arose that require changes that are more appropriate for the main
recipe and not a bbappend.

1) Stop looping over TEST_LIST ourselves and use the TARGETS="" provided
by the kernel-sefltest Makefiles.  This correctly sets up various
variables that the selftest Makefiles all need.  Also, do_install
becomes cleaner because the main Makefile already installs the list of
tests and the top level script.

2) Add DEBUG_PREFIX_MAP to the CC setting to avoid some "buildpaths" QA
errors.

3) Add two INSANE_SKIPS for "already-stripped" and "ldflags".  Some of
the selftest Makefiles are adding flags to their compiles that basically
break the above checks.  Since these compiles are not really meant as
user level tools and instead testing, it should be ok to just always set
INSANE_SKIP for these two.
