configs/galileo: add CONFIG_LBDAF=y in the kernel configuration

Kernel help-text states, "The ext4 filesystem requires that this feature
be enabled <...> otherwise, it will refuse to mount in the read-write
mode any filesystems that use the huge_file feature, which is enabled by
default by mke2fs.ext4."

If the rootfs is to be (re)mounted rw at boot, this must be set for the
system to successfully come up.
