[disco/master-next 6/9] UBUNTU: [Packaging] dkms-build -- add support for unversioned overrides

[Andy Whitcroft]

We allow package specific overrides for dkms-build.  However some
packages have versions in their names.  To make these easier to handle
when the version changes add optional unversioned overrides.  Where a
package ends with a -NNN version look for overrides in the full name
and with a (literal) -N suffix.
