meson: add proper cereal dependency
There are source files that assume cereal header files will be present
without the meson build explicitly finding that dependency. This leads
to compile failures when using the meson-subproject based build. Add a
proper dependency and wrap file for this, based on similar code found in
phosphor-logging.
