fng-install: Fix partitioning when no yocto partitions are found.

When no yocto partitions have been found, an error was thrown.
Now the new partitions are created automatically.

fng-install: Fix output of some messages, move message functions to common

Yocto had the 'logfile' feature, while the other script didn't had this
yet. Also this made some messages for the user end up in the logfile
only, but are needed on stdout also.
This fixes it.
