I have marked this as "high" importance, since it results in a failure
of the core functionality of ubuntu-drivers on specific
hardware+software configurations.

Bug description:
SRU Justification:
[ Impact ]
Attempting to run `sudo ubuntu-drivers install` or `sudo ubuntu-
drivers install --gpgpu` on some machines that support multiple Nvidia
driver version branches can sometimes result in the generated `apt
install` command including multiple conflicting packages, which causes
the installation to be stopped.
[ Test Plan ]
1. On a device with an impacted Nvidia GPU and an impacted Ubuntu
version, run `sudo ubuntu-drivers install`
[ Expected Behavior ]
A working Nvidia driver solution is installed
[ Actual Behavior ]
The `apt install` command does not complete successfully due to an
invalid set of packages being requested for install
[ Fix ]
Before passing the to_install package list to `apt install`, filter
out all but the first packages matching `nvidia-driver-*` since only
one such package should be allowed in a valid solution.
[ Where problems could occur ]
If the Nvidia driver packaging in the archives is ever updated in the
future to allow for multiple valid packages with this glob pattern,
this filtering mechanism would potentially prevent such solutions from
being recommended.
