[PATCH] perf loongarch: Fix build failure with CONFIG_LIBDW_DWARF_UNWIND

[WANG Rui]

Building perf for LoongArch fails when CONFIG_LIBDW_DWARF_UNWIND is
enabled because unwind-libdw.o is still referenced in
arch/loongarch/util/Build.

Fixes: e62fae9d9e8 ("perf unwind-libdw: Fix a cross-arch unwinding bug")
