[libvirt PATCH 17/26] meson: Rewrite libacl check

[Andrea Bolognani]

libacl is Linux-only, so we don't need to explicitly check for
either the target platform or header availability, and we can
simply rely on cc.find_library() instead. The corresponding
preprocessor define is renamed to more accurately reflect the
nature of the check.
