env: Provide a work-around for unquoting fdtfile
Some boards use a CONFIG option to specify the value of this variable.
This is normally handled by efi_get_distro_fdt_name() but in the case
of sunxi this does not work, since 'soc' is sunxi, but the files are
in the allwinner directory.
Provide a work-around for this particular case.
