Trivial fix for out-of-tree build that I wasn't testing previously:

1. Create a directory for library object files, fixes:

gcc lib/kconfig.c -Wall -O2 -g -D_GNU_SOURCE -fno-strict-aliasing -I ../../../../../usr/include/ -iquote /tmp/kselftest/kselftest/net/tcp_ao/lib -I ../../../../include/ -o /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o -c Assembler messages: Fatal error: can't create /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o: No such file or directory make[1]: *** [Makefile:46: /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o] Error 1

2. Include $(KHDR_INCLUDES) that's exported by selftests/Makefile, fixes:

In file included from lib/kconfig.c:6: lib/aolib.h:320:45: warning: ‘struct tcp_ao_add’ declared inside parameter list will not be visible outside of this definition or declaration 320 | extern int test_prepare_key_sockaddr(struct tcp_ao_add *ao, const char *alg, | ^~~~~~~~~~

...

3. While at here, clean-up $(KSFT_KHDR_INSTALL): it's not needed anymore since commit f2745dc0ba3d ("selftests: stop using KSFT_KHDR_INSTALL")

4. Also, while at here, drop .DEFAULT_GOAL definition: that has a self-explaining comment, that was valid when I made these selftests compile on local v4.19 kernel, but not needed since commit 8ce72dc32578 ("selftests: fix headers_install circular dependency")
