Building syslinux against gnu-efi 3.0.10 currently fails with:
syslinux/efi/main.c:33:8: error: unknown type name jmp_buf
33 | static jmp_buf load_error_buf;
| ^~~~~~~
syslinux/efi/main.c: In function local_boot:
syslinux/efi/main.c:189:5: warning: implicit declaration of function longjmp [-Wimplicit-function-declaration]

make[3]: *** [syslinux/mk/efi.mk:63: main.o] Error 1
This is due to gnu-efi commit 486ba3c3bdd147b7d98159b9e650be60bce0f027
("Do not include efisetjmp.h on efi.h"), in which they state:
Do not include efisetjmp.h on efi.h
People than really want to use efisetjmp implementation can include
the header on their own.

So we act as specified, and include <efisetjmp.h> from efi/main.c.
