configure: make --enable-openal use auto detection

OpenAL is disabled by default, because it supposedly inteferes with
some other configure tests and makes them fail silently.

Previously, --enable-openal followed configure's utterly braindead
semantics and disabled auto detection. However, since OpenAL was
disabled by default, there was no easy way to enable OpenAL at all,
even if it was explicitly requested. Solve this by making
--enable-openal use auto detection.
