Memory file system returns Uint8List from readAsBytes

Before this CL the memory file system would return a list - not a
Uint8List - when answering `readAsBytes`.
This for instance caused the ~5.5MB kernel platform file to take up
~42.5 MB of memory (at least on a 64 bit linux system).

This CL changes that to return a Uint8List, saving ~37 MB of memory
when using the kernel platform file, as for instance done when running a
dart file with the VM.
