PR10228: use task_finder_vma for -d /user/object files.

* main.cxx (main): For "-d /path" arguments, enable task finder.
* runtime/sym.h (_stp_module): Add *vmcb member.
* task_finder{.cxx,.h} (emit_vma_callback_probe_decl): Zap.
* tapset-itrace.cxx, tapset-utrace.cxx: Use unwindsyms_modules
  instead.
* tapsets.cxx (uprobe::emit_module_decls): Ditto.
* translate.cxx (emit_module_init): Emit task finder registrations
  for vmcb's associated with _stp_modules.
  (dump_unwindsyms): Associate vmcbs with user-space unwindsyms entries.
