Log Message:
Just in case, fontconfig is built before X fonts are installed,
have some defaults for fonts.conf (/usr/X11R6/lib/X11/fonts/TTF
and /usr/X11R6/lib/X11/fonts/Type1).

I didn't bump PKGREVISION, because in many cases this will be the
same as if it configure figured it out.

I also considered adding TrueType and freefont, but they aren't
included with default XFree86 installation. Also, I didn't include
other font directories, because fontconfig's directory says it's
for outline fonts (.pf*, .tt* and .ot*) and to use local.conf or
~/.fonts.conf for bitmap fonts.

This closes PR #22927 where fontconfig's fc-cache has missing
directories causing font information caches to not be built (using
defaults).
