This first patch in this series adds 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.
The second patch in this series changes lib.mk run_tests target to set
KSFT_TAP_LEVEL before running tests.

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.

Set KSFT_TAP_LEVEL before running tests to prevent nested TAP header
printing from tests.
