shell32: Move _SHCreateSymbolicLinks() above shell folders lookup functions. 

Looking up shell folders creates real directories when the folder is
inexistant, but the intended behavior for some folders is to create
symbolic links by default. Prepare that change by moving the helper
function above shell folders lookup functions. Also fix whitespace
issues in the moved code.

* wine's 'My Documents' to point there. Furthermore, we infer that the user

* - If there is no 'My Documents' directory in $HOME, we let 'My Documents'
* point directly to $HOME. We assume the user to be a unix hacker who does not
* want wine to create anything anywhere besides the .wine directory. So, if
* there already is a 'My Music' directory in $HOME, we symlink the 'My Music'
* shell folder to it. But if not, then we check XDG_MUSIC_DIR - "well known"
* directory, and try to link to that. If that fails, then we symlink to
* $HOME directly. The same holds for 'My Pictures', 'My Videos' etc.
* - The Desktop shell folder is symlinked to XDG_DESKTOP_DIR. If that does not
* exist, then we try '$HOME/Desktop'. If that does not exist, then we leave
* it alone.
