[dts] [PATCH v3 02/27] framework dut and project_dpdk: using correct available binding scripts

[Angela Czubak <aczubak@caviumnetworks.com>]

Below patch makes scripts look for correct DPDK binding script,
checking whether 'usertools' or 'tools' directory is present and which
script exist in 'tools' directory ('dpdk-devbind.py' or
'dpdk_nic_bind.py'). Looking for correct pathc is done in get_dpdk_bind_script method.
