Tweak the generated Errno.pm slightly. Shorter and slightly fewer ops.

Use our directly at the first assignment, rather than on a line by itself.
Add editor readonly blocks, consistent with most other generated files.
require Exporter, rather than using it with an empty import list. We don't need
it at compile time.
