[yocto] [yocto-autobuilder][PATCH] README: Add information for connection managers and tap interfaces

[mariano.lopez at linux.intel.com]

From: Mariano Lopez <mariano.lopez at linux.intel.com>

Lately there are a lot of ping failures in errors.yoctoproject.org,
these seems to be related with the tap interfaces not being managed
correctly.

This just add some information to avoid the connection manager to
manage the tap interfaces created for the yocto autobuilders.
