Make /acct have 0555 permissions after mounting

This change adds a `chmod 0555 /acct` just after mounting the cgroup fs
on it. This makes it such that even on systems where the rootdir+system
partitions are shared, the permissions allow for the system user to open
files within /acct, which in turn makes libprocessgroup not complain
that it can never do anything with those files.

Test: adb shell 'ls -ldZ /acct'  # Before and after, on an aosp_sailfish
      dr-xr-xr-x 48 root root u:object_r:cgroup:s0 0 1971-12-29 17:41 /acct
