[PATCH] perf unwind-libdw: Fix stale object reference in arch/loongarch

[Icenowy Zheng]

The arch/loongarch/util/unwind-libdw.c file is already moved to util/,
but the Build statement for it is forgot to be removed.

Remove the stale Build statement.

This fixes the build failure of perf tool in kernel v7.0 on LoongArch.
