[cairo] Make check on OS/2 revisited

[Dave Yeo]

So I've solved the problem of make check failing on OS/2. Seems to be
the EXTRA_PROGRAMS declaration in test/Makefile.am. Changing it to
check_PROGRAMS like so

-EXTRA_PROGRAMS = $(TESTS) $(SUPPORT_PROGS)
+check_PROGRAMS = $(TESTS) $(SUPPORT_PROGS)

 # Do a funny transition of CAIRO_TEST_TARGET through TARGETS such that
 # one can limit tested targets both through CAIRO_TEST_TARGET env var

Fixes the compile problems. Still need to fix the enviroment so the DLL
is found.
