use layer cache when building images

to more closely mimic docker default behavior, the --layers
cli option is set to true by default for podman.  the buildah
environment variable of BUILDAH_LAYERS is still honored and will
override the command line input.

this should be considered in place of PR #1383.

Many thanks for Scott McCarty for inspiring this welcome change.
