LU-18338 build: fix Ubuntu kernel signature check

The Ubuntu kernel signature was checked by searching for
CONFIG_VERSION_SIGNATURE from autoconf.h. However, in
Ubuntu kernel 6.11.0-061100-generic, CONFIG_VERSION_SIGNATURE
is not defined. We can search for UTS_UBUNTU_RELEASE_ABI
from utsrelease.h.
