Fix typo in C API

[turbolent]

The function BinaryeGlobalImportGetModule should be called BinaryenGlobalImportGetModule (missing n), leading to a linking error, as the function is called properly called BinaryenGlobalImportGetModule:

binaryen/src/binaryen-c.cpp

Line 2866 in 9495b33

const char* BinaryenGlobalImportGetModule(BinaryenGlobalRef import) {

Thanks @turbolent!

We should have more comprehensive tests for these things eventually...

@kripken no worries!

I'm working on a Swift wrapper and it's a real pleasure to wrap such a comprehensive API. Thank you for the great work!

@turbolent nice, very cool!
