  RT: trymmap should retry if the result is out of range

An address passed to `mmap` is just taken as a hint, and the OS may
return something wildly different if that address is not available.
This is undesirable when we're trying to create a constrained alloc.

Now we will check that the address is in the requested range before
accepting it.  Otherwise, unmap it and try a new hint.
