selftests/bpf: Make bpf_dynptr_is_rdonly() prototyype consistent with kernel

Browse Source 
Currently kernel kfunc bpf_dynptr_is_rdonly() has prototype ...

  __bpf_kfunc bool bpf_dynptr_is_rdonly(struct bpf_dynptr_kern *ptr)

... while selftests bpf_kfuncs.h has:

  extern int bpf_dynptr_is_rdonly(const struct bpf_dynptr *ptr) __ksym;

Such a mismatch might cause problems although currently it is okay in
selftests. Fix it to prevent future potential surprise.
