Subject: [PATCH] Change: [Linkgraph] Only acquire thread join performance
 measurements on network clients

Network servers and single player clients do not block on thread joins
due to instead pausing shortly before the join is due.

(cherry picked from commit a5697ddeeb43c64ae6cac25581022efcf8e107bd)
