Ian Lance Taylor 4b3a3bd3aa runtime: don't issue cgocheck error for timer bucket source pointer
The cgo checker was issuing an error with cgocheck=2 when a timer
bucket was stored in a pollDesc. The pollDesc values are allocated
using persistentalloc, so they are not in the Go heap. The code is OK
since timer bucket pointers point into a global array, and as such are
never garbage collected or moved.

Mark timersBucket notinheap to avoid the problem. timersBucket values
only occur in the global timers array.

Fixes #23435
