misc/cgo/testplugin: pass GO_GCFLAGS 

The noopt builder sets GO_GCFLAGS when building the standard library.
Set it when building plugins to ensure the -shared packages built for it
have the same inlining in the export data (and thus the same package
version).

Tested locally with GO_GCFLAGS="-N -l" ./all.bash

Fixes #17937
