move reject with isolation logic in fcntl

This PR moves the block of logic inside `fcntl` to reject if isolation is enabled into the branch checking if the command is `F_FULLFSYNC` on apple. This allows `fcntl` to duplicate file descriptors while using isolation.

This means we can now run the tokio tests with isolation.

This PR allows moves the now passing `fcntl` logic from `libc-fs-with-isolation.rs` into two different tests:
- `fcntl(1, libc::F_DUPFD, 0)` succeeds with isolation
- `fcntl(1, libc::F_FULLFSYNC, 0)` fails with isolation on MacOS
