libcamera: shared_mem_object: Prevent memfd from shrinking or growing
The memfd underlying the SharedMem object must not shrink, or memory
corruption will happen. Prevent this by setting the shrink seal on the
file. As there's no valid use case for growing the memory either, set
the grow seal as well.
