cmd/cgo: don't define intgo in export prologue
The export prologue goes into the _cgo_export.h file, where it may be
be #include'd by a .swig file. As SWIG defines its own type "intgo",
the definition of "intgo" in the export prologue could conflict.
Since we don't need to define "intgo" in the _cgo_export.h file, don't.
Defining "intgo" in _cgo_export.h was new for this release, so this
should not break any existing code.
No test case as I can't quite bring myself to write a test that
combines SWIG and cgo.
