Look for alsoft.conf in the XDG_CONFIG_DIRS and XDG_CONFIG_HOME directories

Browse Source 
This follows the XDG Base Directory Specification. The old files/locations are
still supported, but configs found in XDG_CONFIG_DIRS take precedence over
/etc/openal/alsoft.conf, and a config found in XDG_CONFIG_HOME takes precedence
over $HOME/.alsoftrc.
