[yocto] [yocto-autobuilder][PATCH] checkvnc: use netstat to detect running vncserver

[Joshua Lock]

Using `pidof Xvnc` isn't sufficient because on debian-based distros
the vncserver script will start Xtightvnc.

Instead switch back to using netstat for the VNC tcp socket to
detect a running vncserver.
