Rework XORG_CAT= font
Fonts are now generating the fonts.scale and fonts.dir at install time
font-alias is not needed anymore for the above reason
extract font-util and encodings out of XORG_CAT=fonts because they do not
install any fonts
make XORG_CAT=fonts use USES=fonts
- Rename japanese/jisx0213-fonts with japanese/font-jisx0213.
- Trim old-style header.
- Fix MASTER_SITES.
- Mark as MAKE_JOBS_SAFE=yes
- Remove no-op pkg-req.
