When compiling drivers on Windows, instances have been seen where a
temporary directory fails to get cleaned up due to
ERROR_SHARING_VIOLATION (32).
Code inspection did not reveal problems with the DPDK code and scripts,
and this issue was only seen on Windows. Adding a 1 second sleep before
cleaning up the temporary directory seems to be effective, but to
guarantee that this break does not happen anymore, flag
"ignore_cleanup_errors" is set to "True".
