Andreas Karis 17eab513e9 Skip KUSTOMIZE_PLUGIN_CONFIG_* env variables when too large ...

Kustomize sets the legacy KUSTOMIZE_PLUGIN_CONFIG_STRING and
KUSTOMIZE_PLUGIN_CONFIG_ROOT environment variables. When these
environment variables exceed a hardcoded length (PAGE_SIZE * 32 on most
Linux systems), the kernel will return `argument list too long`. Given
that the environment variables are legacy, log a warning and do not set
them if they exceed 131071 bytes.
