selftest: enable kernel change notifications in the fileserver environment
This environment is currently not used for any test in the smb2
testsuite, so this change doesn't affect any existing test.
A subsequent commit will add a test for change notifications with kernel
change notify enabled. It verifies a bug (this one) that only crops up
in such a setup and causes rename events to get lost.
