module: fix code injection through export names
    
    createDynamicModule() properly escapes import names, but not export
    names. In WebAssembly, any string is a valid export name. Importing a
    WebAssembly module that uses a non-identifier export name leads to
    either a syntax error in createDynamicModule() or to code injection,
    that is, to the evaluation of almost arbitrary JavaScript code outside
    of the WebAssembly module.
    
    To address this issue, adopt the same mechanism in createExport() that
    createImport() already uses. Add tests for both exports and imports.
