util/goroutines: let ScrubbedGoroutineDump get only current stack

Browse Source 
ScrubbedGoroutineDump previously only returned the stacks of all
goroutines. I also want to be able to use this for only the current
goroutine's stack. Add a bool param to support both ways.

Updates tailscale/corp#5149
