test: mbox: LPC reserve memory size is not MTD size

The backing file for the LPC reserved memory region was being allocated
as the size of the MTD device. These sizes are completely unrelated.
The current configuration causes segfaults when the reserved memory
region exceeds the size of the flash.

Instead, resize the backing file once we know how big it needs to be.
Thankfully __init_lpc_dev() doesn't need the file to be sized to the
reported reserved memory size.
