[PATCH] xaudio2: Try to increase OpenAL source limit

[Andrew Eikum]

openal-soft recently added support for applications to request new
source count limits. Older versions will silently ignore these
attributes. Setting this avoids the need for the user to manually
increase the openal-soft source limit. See Bug 39591.
