printf: fix alloca use for windows with mingw32

Don't use just GLIB_HAVE_ALLOCA_H to check if alloca is available,
that's just for the header. GLib may define alloca for us otherwise
too irrespective of GLIB_HAVE_ALLOCA_H.

Fixes compiler warning with mingw32:
gst/printf/vasnprintf.c:73:0: warning: "alloca" redefined
