vsprintf: Move space out of string literals in fourcc_string()

The literals "big-endian" and "little-endian" may be potentially
occurred in other places. Dropping space allows linker to
"compress" them by using only a single copy.

Rasmus suggested, while at it, replacing strcpy() + strlen() by
p = stpcpy(), which is done here as well.
