Subject: PR10000: emit _stp_relocate* calculations correctly for kernel/module
 global $data

* translate.cxx (dump_unwindsyms): Also emit STT_OBJECT symbols,
  therefore .data etc. sections into stap-symbols.h.

* tapsets.cxx (iterate_over_modules): Omit a dwfl_getmodules()
  RC-checking assertion that blocked meaningful $context var
  error messages.
  (dwflpp::emit_address): Bypass dwfl_module_relocate_address()
  for kernel symbols as it has been unreliable; subtract sess.sym_stext
  manually.

* testsuite/buildok/seventeen.stp: Extend test with module $global.
