Subject: [PATCH net-next 5/8] selftests: traceroute: Use require_command()

Use require_command() so that the test will return SKIP (4) when a
required command is not present.

Before:

 # ./traceroute.sh
 SKIP: Could not run IPV6 test without traceroute6
 SKIP: Could not run IPV4 test without traceroute
 $ echo $?
 0

After:

 # ./traceroute.sh
 TEST: traceroute6 not installed                                    [SKIP]
 $ echo $?
 4
