efi: make efi_guid_to_str() take a const GUID pointer

Browse Source 
efi_guid_to_str() only formats the GUID through the byte array passed to
the UUID printf formatter. It does not modify the GUID contents.

Make the input pointer const so callers can stringify GUIDs from const
data without a cast.
