veth.sh is a shell script that uses /bin/sh; some distro (Ubuntu for
example) use dash as /bin/sh and in this case the test reports the
following error:
# ./veth.sh: 21: local: -r: bad variable name
# ./veth.sh: 21: local: -r: bad variable name
This happens because dash doesn't support the option "-r" with local.
Moreover, in case of missing bpf object, the script is exiting -1, that
is an illegal number for dash:
exit: Illegal number: -1
Change the script to be compatible both with bash and dash and prevent
the errors above.
