[OE-core] [PATCH 6/6] rootfs_rpm.bbclass: Update database configuration and initial install

[Mark Hatle]

Move the creation of the database configuration files to just before we
perform the install actions.  This ensures they will exist even in SDK or
other non-target filesystem images.

Also check the initial install actually has something to install, otherwise
this can lead to a failure case.
