tests/Makefile: Remove unused test-obj-y variable
I recently noticed that test-obj-y contains a file called
tests/check-block-qtest.o which simply does not belong to any .c
file and thus wondered why this is not causing any trouble. It is
only used to add -Itests to the command line (which refers to the
build directory). However, it is not needed because "-iquote $(@D)"
already sets this up in rules.mak. Thus we can simply remove this
variable.
