mtd-utils: add ubihealthd to nand-utils

Browse Source 
Add ubihealthd to the nand-utils package, auto-create UCI config for
each UBI device and launch the daemon on boot.

The default time interval between scrubbing a random PED is 120 seconds
which means that a fully used 128 MiB flash chip gets scrubbed in about
a day and a half. The interval can be adjusted in UCI using the
'interval' option.
