README: document that max_bonds=0 is the way to go for bonding.ko
Everything else just is annoying, hence let's list this among the requirements we make on the kernel in order to minimize confusion leading to #6184 and suchlike.

CONFIG_RT_GROUP_SCHED=n
+ It's a good idea to disable the implicit creation of networking bonding
+ devices by the kernel networking bonding module, so that the
+ automatically created "bond0" interface doesn't conflict with any such
+ device created by systemd-networkd (or other tools). Please make sure
+ that the kernel module bonding.ko is shipped with max_bonds=0 set by
+ default. Ideally there would be a kernel compile-time option for this,
+ but there currently isn't. The next best thing is to make this change
+ through a modprobe.d drop-in.

Note that kernel auditing is broken when used with systemd's
container code. When using systemd in conjunction with
containers, please make sure to either turn off auditing at
