kernel-selftest: fix various issues

* respect PACKAGECONFIG when setting TEST_LIST
* call the sed in remove_clang_related only when bpf PACKAGECONFIG is
  enabled and if ${S}/tools/testing/selftests/bpf/Makefile doesn't exist
  then show more useful error message than:
  sed: can't read kernel-selftest/1.0-r0/kernel-selftest-1.0/tools/testing/selftests/bpf/Makefile: No such file or directory
  because kernels older than 4.10 don't have bpf selftest which was
  added in:
  https://github.com/torvalds/linux/commit/5aa5bd14c5f8660c64ceedf14a549781be47e53d
* disable ldflags QA errors, the selftests Makefile explicitly overrides
  LDFLAGS to empty:
  https://github.com/torvalds/linux/blob/5aa5bd14c5f8660c64ceedf14a549781be47e53d/tools/testing/selftests/Makefile#L46
  and the vm/Makefile doesn't respect LDFLAGS anyway:
  https://github.com/torvalds/linux/blob/5aa5bd14c5f8660c64ceedf14a549781be47e53d/tools/testing/selftests/vm/Makefile#L17
  so it was causing a lot of errors:
