Previously, ttmkfdir's output was redirected to fonts.dir,
while the correct behaviour is to let it create fonts.scale
and then let mkfontdir merge fonts.scale into fonts.dir.
type1 handling had a similar problem.
Get the wanted behaviour by automatically appending the contents of
FONTS_TTF_DIRS and FONTS_TYPE1_DIRS to FONTS_X11_DIRS.
Also, save a subshell in install/fonts while there.
Bump PKGREVISION for all affected packages.
jmmv@ says ok.
