This patch does two things. The first removes the snap update code from updateService.linux.ts.
This is because the code always creates a SnapUpdateService if the environment variables are set. This occurs in vscode/src/vs/code/electron-main/app.ts.
The second change this patch introduces is the removal of spawning processes based on $SNAP_NAME. This is because an attacker could potentially leverage the environment variables SNAP, SNAP_REVISION and SNAP_NAME to enable execution through doQuitAndInstall.
I have instead replaced $SNAP_NAME with path.basename(process.argv[0]). This should be equivalent and should just return the name of the executing process. This will preserve the original behaviour whilst remaining compatible with all the various SNAP update mechanisms. This provides better guarantees of executing vscode than some other arbitrary program.
