selftests: vm: fix clang build error multiple output files
[ Upstream commit 1c4debc443ef7037dcb7c4f08c33b9caebd21d2e ]
When building the vm selftests using clang, some errors are seen due to
having headers in the compilation command:
clang -Wall -I ../../../../usr/include -no-pie gup_test.c ../../../../mm/gup_test.h -lrt -lpthread -o .../tools/testing/selftests/vm/gup_test
clang: error: cannot specify -o when generating multiple output files
make[1]: *** [../lib.mk:146: .../tools/testing/selftests/vm/gup_test] Error 1
Rework to add the header files to LOCAL_HDRS before including ../lib.mk,
since the dependency is evaluated in '$(OUTPUT)/%:%.c $(LOCAL_HDRS)' in
file lib.mk.
