When build kvm selftests in tools/testing/selftests directory with
make O=/home/lxy/kselftests TARGETS=kvm
it fails building some kvm test binaries due to lack of header files,
e.g.,
x86_64/vmx_set_nested_state_test.c: In function ‘set_default_vmx_state’:
x86_64/vmx_set_nested_state_test.c:85:7: error: ‘struct
kvm_nested_state’ has no member named ‘hdr’
state->hdr.vmx.vmxon_pa = 0x1000;
...
With "O" is specified, it also takes effect on "make headers_install",
which causes no header files generated in "kernel-src/usr".
Fix INSTALL_HDR_PATH with correct path for this case.
Opportunistically fix the case when KBUILD_OUTPUT specified as well,
even though it can work currently.
