[PATCH] linux-custom: Set KERNEL_CONFIG_TARGET at build time

[Uladzimir Bely <ubely@ilbers.de>]

Expanding KERNEL_CONFIG_TARGET variable at parse time doesn't properly
work while it may need some config file in workdir that is not created
at this moment.

This patch removes the variable from template vars and sets in in
debian/isar/configure at build time
