Daniel Bertalan 304c03f457 Kernel: Reject writable shared file mappings 
We have no way of writing changes to memory-mapped files back to disk,
and software relying on this functionality for output would fail
miserably. Let's just return ENOTSUP instead to allow callers to fall
back to standard file IO instead of silently discarding writes.

This makes the LLD port work, which uses memory-mapped files to write
its output by default.
