tcpdump chroots into /var/lib/tcpdump
When invoking tcpdump, the application creates a netlink_socket and then chroots
into /var/lib/tcpdump.
Without the right to create a netlink_socket:
tcpdump: Can't open netlink socket 13:Permission denied
Without the right on dac_read_search and sys_chroot:
tcpdump: Couldn't chroot/chdir to '/var/lib/tcpdump': Permission denied
