[fonts]: Drop excess `*U` mapping in PS/PDF.

* font/devps/S:
* font/devps/symbolmap: Drop excess mapping of `*U` special character.
  groff maps it to the Adobe Glyph List name 'Upsilon1'.  (The AGL
  'Upsilon' is a homoglyph of the Latin capital 'Y'.)
* PROBLEMS: De-document build-time warning, now resolved.

-This is a known issue with the font mapping groff uses for PostScript
-fonts.  The Adobe Type 1 Symbol font has two different code points for a
-Greek capital upsilon; one looks like a Latin capital Y ("Upsilon"), and
-the other has a curly right arm ("Upsilon1").  In troff systems, only
-one form of Greek capital upsilon is supported; a Latin capital Y is
-used for its Greek homoglyph, whereas the special character '\[*Y]'
-accesses the curly form of the Greek capital upsilon.  We plan to
-resolve this (minor) issue in a future release.
