Subject: [PATCH] Twenty Seventeen: Make sure skip link works in all versions
 of Internet Explorer

This also reduces the number of browsers detected and patched with this fix. Most modern browsers have patched this common bug, where an anchor link does not move focus when clicked. Twenty Seventeen will only worry about older versions of Internet Explorer in this regard.

Props afercia, sami.keijonen.

See #38604.
