Subject: [PATCH AUTOSEL 4.19 096/237] selftests/bpf: fix return value comparison for tests in test_libbpf.sh

From: Quentin Monnet <quentin.monnet@...ronome.com>

[ Upstream commit c5fa5d602221362f8341ecd9e32d83194abf5bd9 ]

The return value for each test in test_libbpf.sh is compared with

    if (( $? == 0 )) ; then ...

This works well with bash, but not with dash, that /bin/sh is aliased to
on some systems (such as Ubuntu).

Let's replace this comparison by something that works on both shells.
