[ruby/io-console] Skip building extension on WASI

Browse Source 
WASI does not support concept to provide termios, so it is not possible
to build io/console extension on WASI at the moment.

However, `io/console` is used by many gems, and removing the dependency
from them *conditionally* is impossible. So, this commit adds a
check to skip building `io/console` extension on WASI just to pass `gem
install` for the platform.
