output/jack: remove DLL support

This effectively reverts commit 0f02bbc2fe which was a horrible
kludge for JACK support on Windows.  Maintaining this kludge doesn't
seem worth the trouble (the JACK version was never updated), and
apparently nobody uses this.

-# This class installs just the public headers and a fake pkg-config
-# file which defines the macro "DYNAMIC_JACK".  This tells MPD's JACK
-# output plugin to load the libjack64.dll dynamically using
-# LoadLibrary().  This kludge avoids the runtime DLL dependency for
-# users who don't use JACK, but still allows using the system JACK
-# client library.

-# The problem with JACK is that it uses an extremely fragile shared
-# memory protocol to communicate with the daemon.  One needs to use
-# daemon and client library from the same build.  That's why we don't
-# build libjack statically here; it would probably not be compatible
-# with the user's JACK daemon.
