kbuild: do not add $(srctree) or $(objtree) to header search paths
scripts/Makefile.lib is included not only from scripts/Makefile.build
but also from scripts/Makefile.{vmlinux,modfinal} for building generated
C files.
In scripts/Makefile.{vmlinux,modfinal}, $(obj) and $(src) are empty.
Therefore, the header include paths:
-I $(srctree)/$(src) -I $(objtree)/$(obj)
... become meaningless code:
-I $(srctree)/ -I $(objtree)/
Add these paths only when 'obj' and 'src' are defined.
