fix(steamcmd): address Copilot review feedback on libtinfo symlink fix

- Iterate over all candidate steamcmd dirs (HOME/.steam/steamcmd,
  steamcmddir, HOME/.local/share/Steam/steamcmd) matching the pattern
  used for steamclient.so fixes elsewhere in the module
- Replace '! -f && ! -L' guard with '! -e' so broken/dangling symlinks
  are also repaired rather than silently skipped
- Add mkdir -p before ln in case the directory does not exist yet
- Capture exitcode=$? after ln so fn_fix_msg_end reports failures
