misc/cgo/test: fix test when using GCC 7
With GCC 7 (not yet released), cgo fails with errors like ./sigaltstack.go:65:8: call of non-function C.restoreSignalStack I do not know precisely why. Explicitly declaring that there are no arguments to the static function is a simple fix for the debug info.
