Build of bpf and tc-testing selftests fails when the relative path of

Stop.
Makefiles of bpf and tc-testing include scripts/Makefile.include file.
This file has sanity checking inside it which checks the output path.
The output path is not relative to the bpf or tc-testing. The sanity
check fails. Expand the output path to get rid of this error. The
fix is
the same as mentioned in commit 150a27328b68 ("bpf, preload: Fix build
when $(O) points to a relative path").

Changes in V2:
Add more explaination to the commit message.
Support make install as well.
Does the same happen when you use make kselftest-all?
No, this problem doesn't appear when using make kselftest-all.
As separate output directory build was broken in kernel's top most
Makefile i.e., make kselftest-all O=dir. (I've sent separate patch to
fix this:
https://lore.kernel.org/lkml/20220223191016.1658728-1-usama.anjum@xxxxxxxxxxxxx/)
So people must have been using kselftest's internal Makefile directly to
keep object files in separate directory i.e., make -C
tools/testing/selftests O=dir and in this way the build of these tests
(bpf, tc-testing) fail. This patch is fixing those build errors.
I am unable to reproduce what you are seeing?
make -C tools/testing/selftests O=dir should reproduce this problem.
Applied to linux-kselftest next for Linux 5.18-rc1.
