[OE-core] [PATCH 4/4] rpm-postinsts.bb: enable postinst logging

[Qi.Chen at windriver.com]

From: Chen Qi <Qi.Chen at windriver.com>

Enable postinst logging according to the existence of the file
/etc/.enable_postinst_logging.

In this way, the postinst logging is enabled if 'debug-tweaks' is
in IMAGE_FEATURES, and at the same time, we avoid unnecessary rebuild
if IMAGE_FEATURES is changed.

[YOCTO #4262]
