[PATCH 11/30] qemuxmlconftest: Move mock'd FDs further out

21 May 2026

From: Peter Krempa <pkrempa@redhat.com>

Upcoming patches will introduce use of real FDs for tests. Since the
test will go through many FDs they will collide with the fake ones
allocated randomly in qemuxml2argvmock.

Move them out for now until they are replaced and masked out from the
tests.
