[Fontconfig] [PATCH] fc-list: constify format string

[Mike Frysinger]

We don't free this string anywhere, so mark it const to avoid gcc warnings
and possible bugs in the future (if people did try freeing it).

fc-list.c: In function 'main':
fc-list.c:161:16: warning: pointer targets in assignment
	differ in signedness [-Wpointer-sign]
