meson: add support for building efi modules
This is a very straightforward conversion of the rules in Makefile.am. Generated objects (on arm64) are identical. The only difference in executed commands is that automake uses ld -m elf_x86_64, without us specifying the -m option anywhere. I suspect that using the default for the given linker should be OK, so it's fine to just skip it.
