support FUSE_TMPFILE in the low level API
Note that name hashes and using paths as parameters
makes it very hard to support
anonymous files in the high level API.
Known Issues:
- tests have to bail out when O_TMPFILE is not supported.
This will always be the case with high level passthrough implementations.
- test_create_and_link_tmpfile has to be skipped
due to unidentified problems with github runner
