Remove uudecode make rule for vt fonts

vt(4) fonts are provided in either .bdf or .hex form, and the binary
.fnt file is generated by vtfontcvt at build time.

Add double size 16x32 VGA ROM font

This was created from vgarom-8x16.hex, and should be useful for higher
resolution displays.

Build vt(4) fonts during buildworld

vtfontcvt(8) is now built during buildworld, so can be used as a
bootstrap tool to create vt(4) fonts from source .hex or .bdf font
files, rather than having uuencoded binary fonts in the tree.
