linux-gen: add runtime configuration file
Enables changing ODP runtime configuration options by using an optional
configuration file (libconfig). Path to the conf file is passed using
environment variable ODP_CONF_FILE. If ODP_CONF_FILE or a particular option
is not set, hardcoded default values are used instead. An template
configuration file is provided in config/odp-linux.conf.
Runtime configuration is initially used by DPDK pktio to set NIC options.
Adds new dependency to libconfig library.
