selftests/bpf: Override EXTRA_LDFLAGS for static builds

When running vmtest.sh with static linking, the bpftool_map_access
selftests fail. These selftests are calling the bpftool binary in
tools/sbin/ directly, which results in the following error:

    error while loading shared libraries: libLLVM.so.21.1:
      cannot open shared object file: No such file or directory

To fix this, we need to also build bpftool statically. That can be done
by setting EXTRA_LDFLAGS=-static.
