third_party/efistub: update to use PE entry point

The old efistub used the EFI handover mechanism, which only exists for
x86_64. Since Linux 5.8 x86_64 also supports the standard PE entry point
which works the same for all supported architectures. That also has the
benefit of no longer needing a weird hack to switch to SysV ABI to call
into the kernel.
