mpd: add upstream patch to fix build with libupnp 1.6.24

Add an upstream patch to fix build with libupnp 1.6.24.

libupnp 1.6.24 added some compat helpers for programs making use of
libupnp to support 1.6.x and 1.8.x easier [1].

MPD added its own wrappers in version 0.20.12 [2] which are clashing with the
newly added compat helpers in libupnp 1.6.24.

The patch disables the MPD wrappers for libupnp version 1.6.24+.
