gitlab: greatly expand captured info about CI runner environment

To aid in debugging wierd CI failures we need greater information
about the CI runner environment. It is usually container based
and can have some unexpected characteristics that significantly
differ from a developer's local environment.

This captures the mount list, CPU model, memory information,
device node lists, kernel info, user identity and all environment
variables.

Since this information can get quite large it is not emitted
directly in the logs, rather it is exposed in job artifacts
under the "ci-runner-env" directory.
