ANDROID: Added a note comment about scummvm.ini location

Location is directly inside the app's internal storage folder

I am not sure if I did this by mistake, because I think it would be better for it
to be under the subpath ".config/scummvm" which we do create earlier.
However, this *mistake* makes the file easier accessible via the "LAN" feature,
since otherwise the user has to also enable the "show hidden files" option
and navigate specifically to the ".config/scummvm" subpath
to set it as root for the LAN server, in order to see the scummvm.ini.
In the current way, the user simply has to set the internal app folder
as root for the LAN server.
