selftests: drop khdr make target
Drop the "khdr" make target as it fails when the build directory is a
sub-directory of the source tree. Rely on the "headers_install"
target to have been run first instead.
For example, here's a typical error this patch is addressing:
$ make O=build -j32 kselftest-gen_tar
make[1]: Entering directory '/home/kernelci/linux/build'
make --no-builtin-rules INSTALL_HDR_PATH=/home/kernelci/linux/build/usr \
ARCH=x86 -C ../../.. headers_install
make[3]: Entering directory '/home/kernelci/linux'
Makefile:1022: ../scripts/Makefile.extrawarn: No such file or directory
The source directory is determined in the top-level Makefile as ".."
relatively to the "build" directory, but then the kselftest Makefile
switches to "-C ../../.." so "../scripts" then points one level higher
than the source tree e.g. "linux/../scripts" - which fails obviously.
There is no other use-case in the kernel tree where a sub-directory
Makefile tries to call a top-level make target, and it appears this
isn't really a valid thing to do.
