Norman Feske 20df224b19 dde_rump: increase max I/O request size to 1 MiB
With the increase of MAXPHYS, the rump kernel requests a contiguous
allocation of 2101248 bytes, which exceeds the allocator's block size of
2 MiB.

  Error: backend allocator: Unable to allocate memory (size: 2101248 align: 12)

The patch avoids this corner case by increasing the allocator's block
size to 4 MiB.

Fixes #4613
