Don't overwrite SDLs audio driver selection.

Browse source 
Hardcoding default driver for some of the supported platform is a
remnant of SDL 1.2 and hasn't been necessary since SDL 2.0 a long
time ago. In fact it has a high properbility to break things, SDL
could easily end up with a non working driver.

When `s_sdldriver` is set to the newly introduced value `auto` the
driver is selected by SDL. In all other cases the string is the
driver name which SDL will be forced to.

This doesn't fix existing configs. Since the OpenAL sound backend has
been the default for nearly 15 years and we haven't received bug reports
for some other problem with the SDL sound backend in the past, I'm half
sure that there are next to users out there. These can reset the cvar
by hand if necessary.

Closes #1132.

modern systems like Windows 10 or Linux with PulseAudio.
* **s_sdldriver**: Can be set to the name of a SDL audio driver. If set
to `auto`, SDL chooses the driver. If set to anything else the given
driver is forced, regardless if supported by SDL or the platform or
not.
* **s_underwater**: Dampen sounds if submerged. Enabled by default.
* **s_occlusion_strength**: If set bigger than `0` sound occlusion effects
