kbuild: do not create empty modules.order in the prepare stage
Currently, $(objtree)/modules.order is touched in two places.
In the 'prepare0' rule, scripts/Makefile.build creates an empty
modules.order while processing 'obj=.'
In the 'modules' rule, the top-level Makefile overwrites it with
the correct list of modules.
While this might be a good side-effect that modules.order is made
empty every time (probably this is not intended functionality),
I personally do not like this behavior.
Create modules.order only when it is sensible to do so.
This avoids creating the following pointless files:
scripts/basic/modules.order
scripts/dtc/modules.order
scripts/gcc-plugins/modules.order
scripts/genksyms/modules.order
scripts/mod/modules.order
scripts/modules.order
scripts/selinux/genheaders/modules.order
scripts/selinux/mdp/modules.order
scripts/selinux/modules.order
Going forward, $(objtree)/modules.order lists the modules that
was built in the last successful build.
