plugins: allow getModuleAddr() to enumerate 32-bit modules in WoW64 m…

…ode.

Include TH32CS_SNAPMODULE32 in call to CreateToolhelp32Snapshot.

This fixes module enumeration in getModuleAddr().

Without this flag, if called from a WoW64 process, we'll only see the
64-bit DLLs of the process (i.e., WoW64 specific DLLs) such as:

  ntdll.dll
  wow64.dll
  wow64win.dll
  wow64cpu.dll

and nothing else.

With this flag, we get everything.

Fixes #2437
