[OE-core] [PATCH] gtk+3: don't split immodules if we have none

[Christopher Larson]

From: Christopher Larson <chris_larson at mentor.com>

Currently we don't enable any immodules for gtk+3, yet we unconditionally call
do_split_packages on a nonexistent path. This results in a return value of
None, which it then tries to join, resulting in a TypeError. Only split the
modules if we have any modules to split.
