[OE-core] [PATCH 1/1] distro_features_check.bbclass: show all error info at one time

[kai.kang at windriver.com]

From: Kai Kang <kai.kang at windriver.com>

In distro_features_check.bbclass it checks whether items in
REQUIRED_DISTRO_FEATURES and CONFLICT_DISTRO_FEATURES exist in
DISTRO_FEATURES. But it only shows one required or conflict distro
feature when error occurs. Update to show them all at one time.
