[LTP] [PATCH 1/1] testscripts/network.sh: Don't load tst_net.sh

I suppose loading tst_net.sh was not needed even before. I wonder why this was
ever needed.

It was added in 6538f7ab70 ("network: merge networktests.sh/networkstress.sh
into network.sh") when testcases/lib/test_net.sh (predecessor of
testcases/lib/tst_net.sh) was much simpler (e.g. without netns).

I suppose it was due export LTP_RSH=${LTP_RSH:-"rsh -n"} which was moved from
testscripts/network.sh to testcases/lib/test_net.sh.

LTP_RSH was changed to use ssh internally in 40110018e6 ("tst_net.sh: Remove rsh
support"), but the variable is still used in various legacy files, which don't
even use tst_net.sh. But these files aren't in any runtest file (see below),
therefore it should be safe to merge this.

$ for i in $(git grep -l LTP_RSH |grep -v README); do j=$(basename $i); echo "* $j ($i)"; git grep $j runtest/; done

* udp4-uni-basic01 (testcases/network/stress/udp/uni-basic/udp4-uni-basic01)

Tools in testcases/network/stress/ns-tools/ will be removed once the rest of
testcases/network/stress/{icmp,udp}/ is migrated to use tst_net.sh or removed.

Kind regards,
