[PATCH bpf] selftests/bpf: use bash instead of sh in test_xdp_redirect.sh

From: Björn Töpel <redacted>

The test_xdp_redirect.sh script uses some bash-features, such as
'&>'. On systems that use dash as the sh implementation this will not
work as intended. Change the shebang to use bash instead.

Also remove the 'set -e' since the script actually relies on that the
return value can be used to determine pass/fail of the test.

Fixes: 996139e801fd ("selftests: bpf: add a test for XDP redirect")
