[PATCH:font/bh-ttf] Install a fontconfig snippet to force treating Luxi Mono fonts as monospaced

[Alan Coopersmith]

fontconfig detects multiple character advances in some of the Luxi Mono
fonts, so doesn't think they're monospaced.   This causes problems when
running xterm -fa "Luxi Mono", since it adds :spacing=100 to the pattern
when requesting a font from fontconfig to prefer monospaced fonts.

For the background here, see the thread "fontconfig not recognizing Luxi Mono
 as monospace" on the fontconfig mailing list recently.
