arm64: link with -z norelro regardless of CONFIG_RELOCATABLE
With CONFIG_EXPERT=y, CONFIG_KASAN=y, CONFIG_RANDOMIZE_BASE=n,
CONFIG_RELOCATABLE=n, we observe the following failure when trying to
link the kernel image with LD=ld.lld:
error: section: .exit.data is not contiguous with other relro sections
ld.lld defaults to -z relro while ld.bfd defaults to -z norelro. This
was previously fixed, but only for CONFIG_RELOCATABLE=y.
Fixes: 3bbd3db86470 ("arm64: relocatable: fix inconsistencies in linker script and options")
