Give group/other users access to directories created by File API on Chrome OS.
Give group/other users access to directories created by File API on Chrome OS.

This CL complements a previous CL committed to revision 110740. The
previous CL makes files created by Chrome (via File API) readable by
group and other users on Chrome OS. However, that does not address the
permission issue on directories created by Chrome. Files under
directories created by Chrome are not readable by group and other users
without making the directories accessible by group and other users as
well.

BUG=126401
TEST=Check permissions (i.e. 0711) on directories created by File API.
