[LTP] [RFC][PATCH 4/6] run_shell_tcnt: Add test count also for test_all

[Petr Vorel]

tst_test.sh shell API has TST_CNT=1 also for tests which are using only
$TST_TESTFUNC without $TST_CNT, i.e. when running only a single
function. Follow this approach. This will be reused in the following
commit.

Instead of this, we can just check for 1 or empty:
[ "$1" = 1 -o -z "1" ]
