bts: Recreate resources.conf trx_list with len based on num_trx

We are already doing this for defaults.cfg, but not for resources.conf.
As a result, if we have a trx_list with 2 trx but we have set num_trx=1
(default), parsing will fail later in bsc.cfg.tmpl because
conf_for_bsc_prepare() will pass a trx_list with 2 trx.
