app-text/xpdf: Drop IUSE qt6 (Qt5 build option)

The question remains why we added back an old PDF toolkit with plenty
of known security holes fixed by poppler since forking XPDF-3.

Yeah right, "fixed in xpdf-5" which has not become a thing since 2022.

But at the very least it must not block Qt5 cleanup. Held my nose and
just dropped that.
