Bug description:
  [Impact]
  OBSOLETE_BY in DKMS.CONF not work
  Which also be reported on upstream:
  https://github.com/dell/dkms/issues/81

  [Test case]
  1. add OBSOLETE_BY in DKMS.CONF
  e.g. OBSOLETE_BY="4.15.0-1033"
  2. the kernel module should not be built with kernel greater than the version specified by OBSOLETE_BY
  e.g.
   - user install kernel 4.15.0-1030 and 4.15.0-10360
   - user install kernel oem-wifi-qualcomm-ath10k-lp1803647-4.15-dkms [1] which has OBSOLETE_BY="4.15.0-1033"
   - the kernel module from dkms [1] should only built for 4.15.0-1030, but not for 4.15.0-10360

  [Regression potential]
  None as it used to work, but somehow regression there.
