library/RSL_Types: account lengthof params in ts_RSL_MultirateCfg

In TTCN-3 it's not possible to store templates in records, so in
f_assignment_codec() we match received RSL_IE_MR_CONFIG against the
value (not template!) stored in g_pars.expect_mr_conf_ie.

Because of that, the length field is not being calculated by TITAN
for us, so we need to calculate it in ts_RSL_MultirateCfg ourselves.
Automatic length calculation only works during encoding/decoding
and when matching against a receive template.
