[LTP] [PATCH 5/6] [WIP,RFC] tst_run.sh: Run setup() only once

[Petr Vorel]

Both C API and tst_test.sh shell API run test only once.
Fix shell loader API also to run setup only once.
This reuses functionality added in the previous commit.

Fixes: 8202494493 ("shell lib: Add basic support for test setup")
Signed-off-by: Petr Vorel <pvorel@suse.cz>

NOTE: this is still not working on iterations (-i2), because
static int iterations is from tst_test.c is not propagated to
tst_run_shell.c. I wonder if I should set the value as environment
variable or add it into struct context.
