Add test to verify FUSE and lower FS dentry cache consistencies

Since I5f9b5d7fc05b77df44f74997672f0036e133b5ab after we reduced the
lookup dentry timeout to 0, deleting or renaming files on the lower
filesystem no longer causes cache inconsistencies. The fix would have
been to call libfuse fuse_lowlevel_notify_inval_entry but this is no
longer necessary.

Added regression tests anyways and verfied that reverting the cl
mentioned above breaks the added tests.

Test: atest FuseDaemonHostTest#testVfsCacheConsistency
