[OE-core] [PATCH] man-db: create man db index file

[Kai Kang]

The man db index file doesn't exist, it causes commands whatis, apropos
and 'man -f' don't work as expect:

| root at qemux86-64:# whatis hosts
| hosts: nothing appropriate.

Run command mandb to create man db index file when first boot.
