style.css: Replace obsolete -moz-outline-style property with outline-style

The "-moz-outline-style" property generates an error at the W3C CSS
validator, saying the property doesn't exist. According to
<https://developer.mozilla.org/en/CSS/-moz-outline-style>, this property
is obsolete and the use of "outline-style" is preferred.
