[Crash-utility] [PATCH][v2] Remove __exception_text_start and __exception_text_end for ARM64
__exception_text_start and __exception_text_end is used to group functions
and place according to linker script in such a way to achieve
kprobe blacklist. Linux commit b6e43c0e3129 ("arm64: remove __exception
annotations") has removed __exception_text_start and
__exception_text_end and uses NOKPROBE_SYMBOL() for blacklist kprobes.
So removing references of __exception_text_start and __exception_text_end
for ARM64.
