[Feature Request] Present a valuable error in GUI (lack of cabextract)

[Justinzobel]

Feature Request

When running the installer for BF-V it gave a wine error that wasn't really useful, running lutris -d told me that cabextract was missing. Can this please be presented in the GUI, that way it will make it easier for other users to identfiy what is missing. Also it may help to know what platform Lutris is missing and provide an appropriate error message:
Solus: sudo eopkg install cabextract
Ubuntu: sudo apt-get install cabextract
etc

Expected behavior

Dialog box or error message in the scrolling terminal to indicate the lack of cabextract

Current behavior

Issue is unknown unless user runs Lutris from a terminal and users don't often know how to do this or want to.

System information

Lutris 0.5.2.2 on Solus

if a script uses an external binary then it should have it in the require-binary directive in the installer.
