[LTP] [PATCH 3/3] net/if-mtu-change.sh: set LTP_TIMEOUT

[Petr Vorel]

The default setup (100 * 5 seconds just for sleep) is longer than default timeout.
30 sec for each iteration should be more than enough as a default.

Fixes: fbea02ab5 ("lib/tst_test.sh: setup timeout per test run for the shell tests")
