Fix RVS confinement issues (BugFix)

[pedro-avalos]

Description

• The ROCm Validation Suite snap is strictly confined, so it can't access the configuration templates in /usr/share (where the checkbox deb stores the data files)
  • Previously, the script would run the snap unconfined, but that leads to issues with dependencies/libraries that the snap bundles in, but may not be installed on the system (the LD_LIBRARY path of the snap would not be included with this hack)
  • Based on Add DPDK Provider (New) #2384, I have changed this behavior to copy the config files to the snap common directory when using the RVS snap; however, since these tests are not run by root user, the common directory is the one in home, rather than /var

Resolved issues

• Partly resolves SERVCERT-2057

Documentation

Tests

• Update unit tests
• Lab submissions: https://certification.canonical.com/hardware/202409-35688/submission/478069/ (device has an AMD CPU with some compatibility with ROCm, the submission shows, however, that the data files are being copied and the tool is finding the right files in the accessible directory)
