gh-96005: FreeBSD has ENOTCAPABLE, too

[tiran]

• Issue: gh-96005

[tiran]

Problem: FreeBSD has ENOTCAPABLE, too. This means that the original changeset maps ENOTCAPABLE to PermissionError on FreeBSD as well. We never wrapped the errno, so it should be ok.

     93	ENOTCAPABLE Capabilities insufficient.	An operation on	a capability
	     file descriptor requires greater privilege	than the capability
	     allows.

:robot: New build scheduled with the buildbot fleet by @tiran for commit 0e36363d13a8990e547bbf259719b618e2ec158b :robot:

If you want to schedule another build, you need to add the ":hammer: test-with-buildbots" label again.
