libmatemixer fails when PULSEAUDIO not selected

[Kevin Oberman]

Installation for the updated audio/libmatemixer fails when the PULSEAUDIO
option is not selected. It still attempts to install the pulse libraries:
===>   Registering installation for libmatemixer-1.22.0 as automatic
pkg-static: Unable to access file
/usr/ports/audio/libmatemixer/work/stage/usr/local/lib/libmatemixer/libmatemixer-pulse.a:No
such file or directory
pkg-static: Unable to access file
/usr/ports/audio/libmatemixer/work/stage/usr/local/lib/libmatemixer/libmatemixer-pulse.so:No
such file or directory

Removing these two files from the pkg-plist allows the port to install
