[PATCH] python3targetconfig.bbclass: Extend PYTHONPATH instead of overwriting

[dev@loewen-email.de]

From: Johannes Schrimpf <dev@loewen-email.de>

[YOCTO #15108] -- https://bugzilla.yoctoproject.org/show_bug.cgi?id=15108

Since the latest change, the PYTHONPATH is overwritten instead of extended.
This leads to changed behavior and build errors of recipes where the PYTHONPATH
is set before setup_target_config is run.
