tunnel: libwg-go: use deterministic verdef name

Browse Source 
From the ld.gold source:

  const char* name = parameters->options().soname();
  if (name == NULL)
    name = parameters->options().output_file_name();

That means by default it uses `-o {output}` as the verdef aux name,
which is random every time due to Go's build system. By passing in
`--soname={somethingexplicit}` we can instead have a deterministic
verdef.

This commit makes wireguard-android reproducible.
