Replace Elvish [[ui]]/[[uI]] diphthong

Previously, we used vdiph/ui_4 for [[ui]]; I think the main reason for
that was that I didn’t like how the most common ⟨ui⟩, vdiph/ui, seemed
to almost vanish in “Cuiviénen”. However, vdiph/ui_4 has the curious
property that in some positions, e.g. ⟨uia⟩ in “tuia” or ⟨uil⟩
“tuilindo”, it sounds (to me) more like /ul/ than /ui/. (This also
affects Finnish, which seems to be the only other language that uses
vdiph/ui_4 [a few other languages also use it for [[ui]] but don’t seem
to emit that phoneme in their rules files] – listen to eSpeak NG
pronounce Finnish ”luiun”, for instance.) I eventually found out that
this can be worked around by substantially lengthening the phoneme
(length 500 seems to work in all positions), but this extreme length
(the absolute maximum is just 511) becomes rather noticeable whenever
the ui is used, including in positions where it had sounded just fine
before. Meanwhile, the more standard vdiph/ui can be made to sound
reasonably well in “Cuiviénen” with a much smaller increment to its
length: 290 (as also in ph_lithuanian) instead of 240 (as in ph_base2)
is enough. In this version, [[uI]] sounds acceptable enough for Elvish
⟨ui⟩ in all positions, as far as I can tell.
