FileSystemPermissionTest.java: Add /data/misc/sensor

Ah yes, it's been a long time since I had to update this list,
with SELinux permissions and all pretty much eliminating
world-writable directories. But alas, the security community is all
abuzz with https://www.exploit-db.com/exploits/39340/ , which
relies on a world writable /data/misc/sensor directory.

Hopefully this will be the last time I ever have to update
this blacklist of bad directories. You've had a good life
little FileSystemPermissionTest, thank you for everything
you've done to make Android safer.
