[PATCH v2] selftests: futex Makefile add top level TAP header echo to RUN_TESTS

[Shuah Khan]

Add top level TAP header echo, testname and separator line to make
the output consistent with the common run_tests target.

This change prevents nested TAP13 headers output from individual tests.
Nested TAP13 headers could cause problems for some parsers.

Changes since v1:
- Add export KSFT_TAP_LEVEL to fix nested TAP header problem
  for "make -C" usecase
- Update commit log with details on nested TAP headers.
