[PATCH] bpftool: Fix dependencies for static build

[PATCH] bpftool: Fix dependencies for static build

[Ihor Solodrai]

When building selftests/bpf with EXTRA_LDFLAGS=-static the follwoing
error happens:

  LINK    /ws/linux/tools/testing/selftests/bpf/tools/build/bpftool/bootstrap/bpftool
/usr/bin/x86_64-linux-gnu-ld.bfd: /usr/lib/gcc/x86_64-linux-gnu/15/../../../x86_64-linux-gnu/libcrypto.a(libcrypto-lib-dso_dlfcn.o): in function `dlfcn_globallookup':

make: *** [Makefile:327: /ws/linux/tools/testing/selftests/bpf/tools/sbin/bpftool] Error 2
make: *** Waiting for unfinished jobs....

This is caused by wrong order of dependencies in the Makefile. Fix it.
