Subject: [PATCH 2/2] selftests: bpf: test_kmod.sh: use modprobe on target device

From: Naresh Kamboju <naresh.kamboju@...aro.org>

on ARM and ARM64 devices kernel source tree is not available so
insmod "$SRC_TREE/lib/test_bpf.ko" is not working.

on these target devices the test_bpf.ko is installed under
/lib/modules/`uname -r`/kernel/lib/
so use modprobe dry run to check for missing test_bpf.ko module and
insert for testing.
