[PATCH v4 3/6] argparse: replace flag enum with marco

[Chengwen Feng <fengchengwen@huawei.com>]

The enum rte_argparse_flag's value is u64, but an enum in C is
represented as an int. This commit replace these enum values with
macro.

Fixes: e3e579f5bab5 ("argparse: introduce argparse library")
Fixes: 5357c248c960 ("argparse: parse unsigned integers")
