[vdagent-win PATCH v4 08/19] Use GetModuleHandle to get some functions from user32 library

[Frediano Ziglio <fziglio@xxxxxxxxxx>]

The library is surely already loaded as providing clipboard and
other utilities we need.
Avoid using LoadLibrary that increment the reference so we don't
need to call FreeLibrary to cleanly decrement the reference.
