Exclude several more directories in /data from encryption

Several directories need to be unencrypted so that policy can be set
on their subdirectories, so exclude them all from device-level
encryption.

This also excludes /data/misc, which must be encrypted for security.
However a weird bug with a disappearing /data/misc/vold was blocking
my development, so I included it here in order to make progress. See
b/26673855
