TestInotifyOverflow test fails on newer host systems

[Markus Ueberall]

The included TestInotifyOverflow test unexpectedly fails on newer host systems if the host system's fs.inotify.max_queued_events is greater than 128*1024:

[2022-05-06T11:18:18+0200] root@desktop01:~# sysctl fs.inotify.max_queued_events
fs.inotify.max_queued_events = 1048576

In order to rebuild the package, it's necessary to temporarily modify said system value (e.g., using "sysctl -w fs.inotify.max_queued_events=16384"), which is rather cumbersome -- cf. https://<email address hidden>/msg04669.html

It would be best to remove the above test (or maybe keep it but replace the threshold with an absurdly high number?)
