Network issue delays running the testsuites in luv-netboot-image #124

Even after the interface link ready(according to dmesg), luv-netboot-image takes ~250 secs to start running the testsuites. This can be mistaken for a system hang and hence needed a fix.

Probably this problem can be debugged using the systemd-analyze tool. Luckily, this tool is already in poky. All we have to do is add it to the ramdisk image by adding systemd-analyze.
