stub: drop PE sections parsing cap

This was added originally as it was thought that Windows applied
the same cap. Nowadays the specs do not mention it, and it is
believed Windows no longer applies it either, so drop it in order
to allow an arbitrary number of DTBs to be included

Fixes https://github.com/systemd/systemd/issues/35943

(cherry picked from commit 8c5b359579b0f1029edafb0bd96b5ebfb271db76)
