eficonfig: expose eficonfig_create_device_path()

Browse source 
Following commits are adding support for UEFI variable management
via the eficonfig menu. Those functions needs to use
eficonfig_create_device_path() to construct the full device path
from device path of the volume and file path, so move it
out of their static declarations.
