fng-install: Change bootloader version check to warning for U-boot

U-boot version detection does not always work, as only the installed but not the bootet version can be found out. So we change the message to warning and continue the installation.

Also handle missing /etc/shared folder during installation.

sharedconf:gf-version: Fix u-boot version detection for SDCard based systems.

gf-version uses mmc command to find out if the current bootloader is stored in the p1 or in the boot0 partition. For SDCards the mmc commands fail and make the kernel print useless message.
