FS watch failures on test-ibm-aix72-ppc64_be-2 #4446

Description

@sxa

I've taken https://ci.nodejs.org/computer/test-ibm-aix72-ppc64_be-2/ offline as it is currently showing failures in the FS watch tests. The seem consistent on that machine only as per https://ci.nodejs.org/job/node-test-commit-aix/nodes=aix72-power9/64795/testReport/

Initially raised to me via nodejs/node#65492 (comment)

Sample failure from parallel/test-fs-promises-watch (most of the failures look to be with ENOENT):

    Easily to reproduce outside jenkins so at least it's consistent.

    A reboot (which I had to trigger today as part of testing some system changes as part of #4425) appears to have resolved this, so while we did not identify the underlying cause we can safely re-enable the machine. Done, and closing.
