[PATCH v4 2/3] refactor linux-custom.inc to use ISAR's DEB_BUILD_PROFILES support

[Felix Moessbauer <felix.moessbauer@siemens.com>]

This patch replaces the manual setup of the DEB_BUILD_PROFILES
environment variable in the linux-custom.inc recipe.
Instead, the recently introduced DEB_BUILD_PROFILES infrastructure
of ISAR is used.
