[Crash-utility] [PATCH] arm64: exclude mapping symbols in modules



If some module has been inserted, crash util complains about
module symbols:
    ...
    please wait... (gathering module symbol data)
    crash: store_module_symbols_v2: total: 15 mcnt: 16
and end up with stopping.

This patch excludes mapping symbols, like $d and $x, as arm does.
