UBUNTU: [Packaging] dkms: increase directory prefix max length to 140 characters

Browse Source 
With longer kernel names (such as linux-lowlatency-hwe-5.15) we may
exceed the dkms directory prefix limit of 100 characters, used when we
build zfs for example.

Simply increse this limit to 140 to prevent dkms from multiple flavours
clashing on each other.

Ignore: yes
