Bug 1050398 - remove intl/unicharutil/tools/Makefile.in; r=mshal

EX_LIBS is completely unused, and uses a dodgy mechanism of getting
glib's libraries to boot.  We could have moved the CFLAGS bit over to
moz.build, but the only C file in this directory, ucgendat.c, doesn't
use anything from glib.  So let's just delete the whole thing.
