man: update examples in nilfs.8

Browse Source 
Update the usage examples in the nilfs(8) manual page to reflect current
behavior.

The previous examples were outdated, showing timestamps from 2014 and
mount command output that differs from modern kernel behavior
(specifically regarding the "gcpid" and "relatime" mount options).

This change aligns the examples with the "What is NILFS?" section of the
official website.
