full diff: https://github.com/gofrs/flock/compare/v0.7.1...v0.7.3

Relevant changes:

- fix: close/Unlock won't close the file descriptor if not locked
- fix license text, update year

Note that there's also a v0.8.0 release; that release only adds aix support,
which is currently of no interest to us, so skipping that version for now.
