modprobe.d: ship drop-in to set bonding max_bonds to 0 (#6448)

This allows networkd to correctly manage bond0 using networkd, when requested
by the user.

Fixes #5971 #6184

+# When bonding module is loaded, it creates bond0 by default due to max_bonds
+# option default value 1. This interferes with the network configuration
+# management / networkd, as it is not possible to detect whether this bond0 was
+# intentionally configured by the user, or should be managed by
