inotify-tools: add ptest support for inotify-tools

Add ptest support for inotify-tools by introducing a run-ptest script.
The ptest verifies the correct functioning of inotify event handling
and related utilities.

Test coverage includes:
 - File creation, modification, and deletion event monitoring
 - Event handling and command-line option parsing
 - Basic consistency and behavior of inotify event queues

The ptest completes in under 20 seconds

output:
root@qemux86-64:~# ptest-runner inotify-tools
START: ptest-runner
BEGIN: /usr/lib/inotify-tools/ptest
If you want to do a malloc trace, set MALLOC_TRACE to a path for logging.

for inotify-tools
