www-misc/shellinabox: turn openssl into a hard dependency and remove …

…ssl USE flag.

dev-libs/openssl:0= previously was an optional dependency available through a
USE flag but it turns out shellinabox cannot be compiled with SSL support
disabled. let's remove the "ssl" USE flag and turn dev-libs/openssl into a hard
dependency.
