mesg: avoid 'ttyname failed: Success' message
The ttyname(3) can fail to access /dev/ path, and that will cause function
to fail without setting errno value with result of rather confusing error
message. Lets start setting stdin permission via /proc when this happens as
a go-around, with hope kernel following symlink does not fail. Ok, noted,
that hopes of symlink follow working are pretty slim.
Based on patch from Sami Kerola <kerolasa@iki.fi>.
