runtime: add edge lockRankSysmon -> lockRankRwmutexR
Sysmon can actually get the RW lock execLock while holding the sysmon
lock (if no M is available), so there is an edge from lockRankSysmon to
lockRankRwmutexR. The stack trace is sysmon() [gets sched.sysmonlock] ->
startm() -> newm() -> newm1() -> execLock.runlock() [gets
execLock.rLock]
