As a result of the switch to dh_listpackages, $version is no longer set
when install_kernel_headers() is called.  This causes files in the
linux-headers deb package to be installed to a path with an empty
$version (e.g. /usr/src/linux-headers-/scripts/sign-file rather than
/usr/src/linux-headers-6.3.0-rc3/scripts/sign-file).

To avoid this, while continuing to use the version information from
dh_listpackages, set $version from $package.

Thank you for catching this.
Can you pass it as the second argument to the function?


   install_kerne_headers debian/linux-headers ${package#linux-headers-}

Good idea!  Thanks for the quick review and feedback.  Here's an updated
version.

Changes since v1:
 * Pass version as the second argument to install_kernel_headers(),
   rather than as a global variable, as suggested by Masahiro Yamada.
