stuebinm ff1a94e523 treewide: add meta.mainProgram to packages with a single binary
The nixpkgs-unstable channel's programs.sqlite was used to identify
packages producing exactly one binary, and these automatically added
to their package definitions wherever possible.

longDescription = ''
Automatically assign a dedicated systemd scope to the GUI applications
launched in the same cgroup as the compositor. This could be helpful for
implementing cgroup-based resource management and would be necessary when
`systemd-oomd` is in use.
Limitations: The script is using i3ipc window:new event to detect application
launches and would fail to detect background apps or special surfaces.
Therefore it's recommended to supplement the script with use of systemd user
services for such background apps.
