Even if CONFIG_ULIB is enabled it may not actually be in use. If not,
we still need the EFI-runtime relocation to happen. Adjust the condition
in efi_runtime_relocate() to fix this.
For static linking with ulib examples, provide weak symbol definitions
for __efi_runtime_rel_start and __efi_runtime_rel_stop. These symbols
are normally defined in linker scripts but need fallback definitions
when linking statically against libu-boot.a.
