Subject: [PATCH] RPM: Remove old versions of DKMS on upgrade

Due to a mismatch between the text and a regex looking for that text,
the `%preuninstall` script would never run the `dkms remove` command
necessary to avoid corrupting the DKMS data configuration.  Increase
regex specificity to avoid this issue.

Closes: #9891
