SIGWINCH generates SIGINT

[rendarz]

If we look at the code located here https://github.com/console-rs/console/blob/master/src/unix_term.rs#L325
you should realize that EINTR can be generated also by other signals than SIGINT.
In my application, if I resize the terminal, a SIGWINCH signal is thrown, but your crate translates that SIGWINCH (which generates an EINTR) to a SIGINT, so you're throwing an unwanted SIGINT to the "outselves", causing my application to brutally exit (since it received a SIGINT).
PLEASE FIX THIS!
