[PATCH V2] linux-custom: support to add linux-libc-dev package with kernel name

["'Arulpandiyan Vadivel' via isar-users" <isar-users@googlegroups.com>]

Debian and Ubuntu use unified kernel headers and a single linux-libc-dev
package is shipped. In contrast, Isar may build multiple kernel variants
with different versions and/or patches and their packages.
But linux-libc-dev are suffixed with -${KERNEL_NAME_PROVIDED}: this allows
each variant to exist in isar-apt (reprepro may not have more than one
version of a given package for a given suite).
Apply the same suffix to linux-libc-dev and a Provides: clause.
