Subject: [PATCH] meson: use OpenAL.framework on macOS

It is not picked up by the existing dependency() check because its
version is unknown to Meson, which fails the version constraint.
Besides, dependency('openal') seems to try "openal.framework",
which may or may not work on case-sensitive file systems.
