#9834: bfs sends spurious B_STAT_MODIFICATION_TIME notifications after file
change

Platform: All |
------------------------------+------------------------------
After a file has been changed (or just `touch`ed) BFS starts sending out
`B_STAT_MODIFICATION_TIME` whenever the file is closed after opening it
for writing, even if the file wasn't modified. Can be reproduced with the
attached test programs:
- Start monitoring a file that hasn't been changed in this session, yet:
{{{
modified_time_monitor /path/to/file
}}}
- Verify that no spurious notification are sent yet (the test program
waits 3s before closing the file):
{{{
open_for_writing /path/to/file
}}}
- Touch the file. Notifications are received as expected.
- Run `open_for_writing` again. This time after `close()` a spurious
notification is received.
Tested in the package-management branch, which corresponds to master
hrev45747.
