fix: distro.sh: line 100: [: : integer expression expected (#4486)

* fix: servername variable assignment for sf and unt

The servername variable was incorrectly assigned using the selfname variable instead of the correct servername variable. This has been fixed to ensure accurate information is displayed for each game type.

* [FIX] #4465
