Work around Raspberry Pi kernel packaging oddities

On Debian and Ubuntu and friends, you get something like
"linux-image-$(uname -r)" and "linux-headers-$(uname -r)" you
can put a Depends on.

On Raspberry Pi OS, you get "raspberrypi-kernel" and
"raspberrypi-kernel-headers", with version numbers like 20230411.

There is not, as far as I can tell, a reasonable way to map that
to a kernel version short of reaching out and digging around in
the changelogs or Makefile, so just special-case it so the packages
don't fail to install at install time. They still might not build
if the versions don't match, but I don't see a way to do anything
about that...
