nptl: Skip pretty-printer tests without python3 [BZ #34507]

Browse Source 
The tests-printers-out rule in Rules wraps $(PYTHON) through
$(test-wrapper-env).  Unlike ordinary tests, which wrap a freshly built
target binary, this wraps python3, a build-host tool.  When cross-testing
with test-wrapper set (e.g. via scripts/cross-test-ssh.sh) the whole
command is forwarded to the target; if the target lacks python3 the shell
returns 127 and evaluate-test.sh reports the six nptl pretty-printer
tests as FAIL instead of UNSUPPORTED.

scripts/test_printers_common.py already exits UNSUPPORTED (77) when its
dependencies are missing, but that is unreachable when python3 itself is
absent.

Guard the invocation with a "command -v" check so the recipe exits 77
(UNSUPPORTED) when python3 is not found.  Native builds are unaffected,
as configure requires python3.
