Subject: [PATCH] cli: fix FTBFS on Windows

It has a stub for SIGHUP, but doesn't have anything for USR1 and USR2:

Error: cli\server\server.go:520:31: undefined: syscall.SIGUSR1
Error: cli\server\server.go:521:31: undefined: syscall.SIGUSR2
Error: cli\server\server.go:565:17: undefined: syscall.SIGUSR1
Error: cli\server\server.go:608:17: undefined: syscall.SIGUSR2
