upgpkg: shim-efi-git 15.r204.758b795a-1: disable buildflags, add gnu-efi submodule

- Upstream is back at using vendored libraries, this time for gnu-efi :(
- Building with the default Arch Linux buildflags fails with the following
  error, so disable them (they are not very meaningful for EFI binaries
  anyway):

/build/shim-efi-git/src/shim/gnu-efi//lib/print.c:1242:17: error: SSE register argument with SSE disabled
