Ilya Leoshkevich cb4969e6f9 selftests: fix prepending $(OUTPUT) to $(TEST_PROGS)
Currently the following command produces an error message:

    linux# make kselftest TARGETS=bpf O=/mnt/linux-build
    # selftests: bpf: test_libbpf.sh
    # ./test_libbpf.sh: line 23: ./test_libbpf_open: No such file or directory
    # test_libbpf: failed at file test_l4lb.o
    # selftests: test_libbpf [FAILED]

The error message might not affect the return code of make, therefore
one needs to grep make output in order to detect it.

This is not the only instance of the same underlying problem; any test
with more than one element in $(TEST_PROGS) fails the same way. Another
example:

    linux# make O=/mnt/linux-build TARGETS=splice kselftest
    [...]
    # ./short_splice_read.sh: 15: ./splice_read: not found
    # FAIL: /sys/module/test_module/sections/.init.text 2
    not ok 2 selftests: splice: short_splice_read.sh # exit=1

The current logic prepends $(OUTPUT) only to the first member of
$(TEST_PROGS). After that, run_one() does

   cd `dirname $TEST`

For all tests except the first one, `dirname $TEST` is ., which means
they cannot access the files generated in $(OUTPUT).

Fix by using $(addprefix) to prepend $(OUTPUT)/ to each member of
$(TEST_PROGS).
