[bug#62298] [PATCH 6/8] services: mpd: Set PulseAudio related variables as default value for environment-variables field.

[Bruno Victal <mirai@makinata.eu>]

These variables are necessary for PulseAudio to work properly out-of-the-box
for 'non-interactive' users.


* doc/guix.texi (Audio Services): Update environment-variables field description for
mpd-configuration data type.
* gnu/services/audio.scm (mpd-configuration)[environment-variables]: Set
PULSE_CLIENTCONFIG and PULSE_CONFIG environment variables to the system-wide
PulseAudio configuration.
