installer: welcome: Warn when uvesafb gets used. 

There will be false positives: Because the Guix installer uses the
kernel argument modprobe.blacklist=radeon,amdgpu and some AMD graphics
actually work okay according to h-node, these users will get a
false alarm.

* gnu/installer/newt/welcome.scm (run-welcome-page): Warn before showing
the welcome page.
