Chris Lu b21c263328 test/fuse_dlm: cross-mount POSIX locks + survival across a ring change (#9677) ...

Adds two FUSE integration tests on the existing dlm cluster harness (the
-dlm mounts route advisory locks to the owner filer):

- TestPosixLockCrossMount: an flock taken on one mount blocks the other,
  and is grantable after release — the routed-to-owner path end to end.
- TestPosixLockSurvivesFilerLoss: hold flocks on many files, stop filer1
  so keys it owned migrate to filer0; after the ring settles and the
  holding mount re-asserts, every lock is still honored. Asserts only the
  settled state; the transient migration window is unit-covered.

Locks are taken on read-only fds so the -dlm whole-file write lock (a
different mechanism, held until close) isn't involved. Skipped on
non-Linux: only Linux forwards advisory locks (SETLK) to the FUSE server;
macFUSE handles flock in-kernel per mount.
