services: mpd: Do not hardcode environment variables.
Services should not expect for XDG_RUNTIME_DIR to be set.
Inferring from the past comment, this seemed to resolve an issue when
the service was launched with an _interactive_ user-account,
which tends to have this variable set by the login-manager.
This is not the case for system accounts and setting this variable
results in PulseAudio (launched by the same system user) failing to start
since it attempts to use a nonexistent directory.
Ideally, this service should have a home-service counterpart but the old
behavior can be emulated by setting the environment-variables field to:
(environment-variables
(list
(string-append "XDG_RUNTIME_DIR=/run/user/"
(number->string (passwd:uid (getpwnam "myuser"))))))
* gnu/services/audio.scm
(mpd-configuration)[environment-variables]: New field.
(mpd-shepherd-service)[start]: Use new field.
* doc/guix.texi (Audio Services)[Music Player Daemon]: Document it.
