make the -t (/tmp mount) option imply -v (new mount namespace)
The current -t option will happily mount /tmp in the same mount namespace
which is pretty much never desired. Make it imply -v like other options.
Also fix up some outdated man page docs -- /tmp is mounted with 64MB.
Bug: None
Test: `minijail0 -vt -- /bin/sh -c 'mount; ls -ld /tmp'` shows /tmp mounted
Test: `minijail0 -t -- /bin/true` no longer remounts /tmp outside of the mount
