Subject: [PATCH] kvargs: remove experimental function to compare string

The function was designed to be used as a handler for
rte_kvargs_process() to compare the value string in a kvlist. For
readability, its usages in DPDK have been replaced by
rte_kvargs_get_with_value() in previous commit.

Remove this function, as it is not used anymore.
