inotify-tools: improve ptest result handling

The run-ptest script determines success by grepping for
"0 failed" in the test output. This could incorrectly
report success for cases like "10 failed" or "100 failed".

Update the script to rely on the test binary's exit status instead,
while still capturing and printing full test output for logging.

This makes the ptest behavior more robust and consistent
