Ensure all log messages not filtered by top-level .level property are written to disk
Ensure all log messages not filtered by top-level .level property are written to disk

Summary:
I noticed this when I was working on D1425063.

If an engineer wants to get verbose logs on disk, they currently need
to change both the ".level" property which controls which log messages
are dropped at the root level, as well as the
"java.util.logging.FileHandler.level" property.

With this diff, the FileHandler now logs anything not otherwise filtered
by the top-level ".level" property, so you only to to change ".level"
to get more verbose logs written to disk.

Test Plan:
Edited config/logging.properties, set .level=FINER.
Ran 'buck build buck'. Confirmed verbose logs were written to disk.
Reverted change, ran 'buck build buck', confirmed verbose logs were
not written to disk.
