Currently dpdk_nic_bind.py detects Linux kernel modules via reading
/proc/modules. Built-in ones aren't listed there and therefore they are
not being found by the script.
Add support for checking built-in modules with parsing the sysfs files.
This commit obsoletes the /proc/modules parsing approach.
