XmlUtils#readThisMapXml should handle null keys.

Both readThisValueXml & writeThisValueXml have been
implemented to handle values with "null" names.

Change readThisMapXml to allow such names as well, and
map them to the null key in the resulting HashMap.
readThisListXml and readThisSetXml already support
null names.

Revert "Remove the navigation camera icon in keyguard if disabled by DPM"

This reverts commit 6eef309ae2e85e96f276b18a4f989f2086e2cf9c. The camera
widget itself not showing is a bug with the lock screen. The navigation
icon should be displayed.
