[Matthias Baesken]

Hello, please review this small fix for a build error on 32bit Windows.
Currently we run into 
d:\test\hotspot\jtreg\serviceability\jvmti\DynamicCodeGenerated\libDynamicCodeGenerated.cpp(49): error C2373: 'Agent_OnLoad': redefinition; different type modifiers
d:\jdk-dev-build\support\modules_include\java.base\jvmti.h(51): note: see declaration of 'Agent_OnLoad'
