[LTP] [RFC PATCH 2/3] net/ipsec_lib.sh: Use positional parameters in TST_PARSE_ARGS function

[Petr Vorel]

as it's now supported also for legacy API.

Major problem was with using global $opt instead of $1 (dependency on
how the library function implemented), but avoiding using $OPTARG
directly is also preferable.
