init: Force 0755 permissions of /var/cache [Merge to M52]
/var/cache may already exist with wrong permissions before mkdir is
executed, which will be ignored, and the permissions won't be set correctly.
This leads to extensions and apps not being synced correctly on certain devices.
This CL enforces the correct permissions of /var/cache.
BUG=chromium:617823
TEST=cros_workon_make
TEST=manually by setting /var/cache to 0700, restarting device, adding a new account,
and seeing apps and extensions being synced successfully.
