Error message

the libdrmtap being packaged is {so_ver[0]}.{so_ver[1]}.{so_ver[2]}, which the runtime loader would REFUSE: drmtap_dl.rs accepts exactly major {major}, minor {minor}, patch >= {floor[1]}. Shipping it produces a deb whose DRM capture can never start. Move the build pin and the gate together, or fix whichever one is wrong.
