Font glyphs sometimes disappear in CHERI desktop environment

[jrtc27]

Sometimes, specific font glyphs will stop being rendered, whilst others remain completely functional. Possibly relevant is this definitely-bogus diff in fontconfig that should be reverted either way:

cheribsd-ports/x11-fonts/fontconfig/files/cheribsd.patch

Lines 182 to 196 in 1aeef3a

#98 may or may not fix this. Time will tell. It does not, but CTSRD-CHERI/cheribsd#1827 is promising.

FYI, I just got the missing glyphs when waking my desktop back up while in sddm with CTSRD-CHERI/cheribsd#1827 applied.
