fix: let a declared size contest another size

Browse Source 
System.dat pins the 2 KiB X1 font as xmil/IPLROM.X1T, where xmil reads
a 32 KiB Turbo IPL. A held copy of the exact size a profile declares now
proves its claim against a file of another size, so the existence packs
ship the IPL. The font's duplicate under the IPL name is removed.
