ipxe: correct licensing information

Updates the licensing information to match Fedora's SPDX
identifier. This is necessary because of IPXE's built-in EFI
headers and other third-party code embedded in IPXE. Please
note that Nixpkgs does not yet have a way to programatically
identify `GPL-2.0-or-later WITH UBDL-exception` or the `AND`
and `OR` logical identifiers in SPDX, so the best we can do
is express all of the licenses in a list and add a comment
for UBDL.
