Interpret config file/args as relative to pkg_dir

Interpret the config file path as relative to the
ClimaCOupler.jl package. Do the same for the restart_dir and
coupler_output_dir in the config.

This enables `run_amip` to also be run from
`experiments/ClimaEarth` with the default config path
and without modifying the usual output path.
