[xtotroff]: Avoid overrunning buffer write.
* src/utils/xtotroff/xtotroff.c (MapFont): Avoid writing past
the end of a static buffer. Problem found and patch supplied by
Bjarni Ingi Gislason. I tweaked it to comment it differently (in case
the buffer ever needs to grow, but the prospects of future X11
server-side font rendering development seem dim) and use snprintf()
instead of retaining the existing sprintf().
Quiets warning: '%s' directive writing up to 255 bytes into a region
of size between 0 and 255 [-Wformat-overflow=].
