Ensure that /data/anr/traces.txt is world-writable 

The umask changed for init. We have to force /data/anr to be world
readble and /data/anr/traces.txt to be world writable so dalvik
processes can write to it.

Hopefully this is a short term change while we investigate tightening
up these permissions.
