selftests: kselftest framework: add handling for TAP header level
Introduce environment variable KSFT_TAP_LEVEL to avoid printing nested TAP headers for each test. lib.mk run_tests target prints TAP header before invoking the test program or test script. Tests need a way to suppress TAP headers if it is already printed out. This new environment variable adds a way for ksft_print_header() print TAP header only when KSFT_TAP_LEVEL isn't set. lib.mk run_tests and test program should print TAP header and set KSFT_TAP_LEVEL to avoid a second TAP header to be printed. selftests Makefile should export KSFT_TAP_LEVEL and add TAP Header echo to the run_kselftest.sh script from emit_tests target handling.
