Tighten up snap permissions

[XioNoX]

The attached screenshot is what shows up in gnome-software about the snap version of Deezer.

I was wondering if access to the download directory could be removed. Ideally the Pictures directory as well.

Note that the app works very well!

Hello, here is what I can do:

• remove the downloads read access (may be used in order to import mp3 into deezer, but that's really not very important as the user can still use the Musics folder)
• remove the picture folder read access (that would prevent the user from upload a profile picture, which is not very ergonomic as the user should then import its picture under 'Musics', and select it... I don't know if that's really wanted)
• I could too remove access to the Musics folders, but then there is really no way to easily upload mp3, so that's not very interesting (and deezer is a music app, so giving it access to the musics folder should be acceptable)
• concerning the use of x11/xwayland (the "legacy" orange flag), there is no much I can do for the moment as electron does not seem to work well under wayland
• and for the proprietary code, there is nothing I can do, as it really is the property of deezer :)

So I will give a go with the first and maybe second points in next version :)
