meson: Enforce sqlite dependency for liblastlog2

liblastlog2 requires the sqlite dependency.
Currently, Meson enforces this dependency to be available only when the
build-liblastlog2 feature is explicitly enabled.
liblastlog2 is built by default, so if sqlite is not available, the
build will be configured correctly, but fail to compile.
This commit fixes this case by automatically disabling the
build-liblastlog2 feature when it is auto and sqlite is not found.
