[PATCH][AB] fix do_libc_dev_package breakage

[Kamal Mostafa]

Our do_libc_dev_package vars feature was broken by debhelper deprecating
dh_clean in favor of dh_prep.

To support custom kernels derived from {Artful, Bionic}, only try to
dh_prep linux-libc-dev if do_libc_dev_package=true.

This results in no changes to the master kernels, just allows derivs to
override standard behaviors.
