[LTP] [PATCH] lib/tst_test.sh: fix ROD_SILENT command return status check

[Petr Vorel]

Hi Alexey,

> "local tst_out=$(some_command)" always returns status 0, i.e.
> not the return status of the command in the assignment, but the
> status for 'local' builtin command, which creates a new local
> variable inside the function.

> As a result, the library calls and tests that invoke ROD_SILENT
> don't actually check the return status of commands passed to it.

Very good catch, thanks!

Tested-by: Petr Vorel <pvorel@suse.cz>
Working the same in: bash, dash, busybox sh, mksh (android).

> The old API library function is also fixed.
