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.
