Steam installs .desktop files that refer to an executable called `steam'.
Installing steam-nvidia as the `steam-nvidia' executable breaks this, which
means Steam cannot be launched from its desktop icon. This also applies to
.desktop files for individual games generated by Steam, when they are copied
from `<ngc-sandbox-home>/.local/share/applications/'.
Fix this by always installing Steam's wrapper executable as `steam'. We add a
new field using "binary" to keep things shorter.
This has the downside that the `steam' and `steam-nvidia' packages cannot be
installed in the same profile, but likely people wouldn't want to do this
anyway.
Fixes#294.
* nongnu/packages/steam-client.scm (steam-nvidia-container)[binary-name]:
Specify for compatibility with .desktop files.
* nonguix/multiarch-container.scm (<nonguix-container>)[binary-name,
ngc-binary-name]: New field and accessor.
(nonguix-container->package): Use it to set correct executable name.
(make-internal-script): Use it in message.
