INSTALL - Always add video group to rdc user

Previously we relied on "render" to be enough and only used "video" as a
fallback. On some systems like SLES this might not be sufficient.

One issue happened when starting rocprofiler as part of RDC
initialization:
  what():  hsa error code: 4104 HSA_STATUS_ERROR_OUT_OF_RESOURCES
The issue only happened when RDC was started with systemd.
Turns out "rdc" user (under which systemctl starts RDC) only had render
but not video group. Adding video group solved the issue.
