Merge #123458

123458: roachprod: fix `start.sh` profile check r=srosenberg,renatolabs a=herkolategan

Previously, multiple entries would be created in "${HOME}/.profile" since the check for "${HOME}/.profile-cockroach" would always fail. This updates the check to look for the correct file based on the virtual cluster label.

Fixes: #121267

Epic: None
Release Note: None
