FindPythonLibs: Search for single-user installs on Windows

When cmake searches for Python libs in Windows it searches in:

  [HKEY_LOCAL_MACHINE\\SOFTWARE\\Python\\PythonCore\\${_CURRENT_VERSION}\\InstallPath]/libs

However, the information might not always reside there.  The information
could also reside in:

  [HKEY_CURRENT_USER\\SOFTWARE\\Python\\PythonCore\\${_CURRENT_VERSION}\\InstallPath]/libs

when one installs Python for a single user and not for all users.
