gollvm: fix handling 128-bit integers in llvm-godumpspec
Skip integer types larger than 8 bytes that appear in newer headers (in
particular, when clang 16 is used to build gollvm).
This prevents handing these types with other integer types when analyzing DWARF
and getting them into runtime_sysinfo.go with further build
failure with "error: use of undefined type 'int128'".
