LU-17095 build: avoid modules.order nonexistence failure

The modules.order is a temporary output file generated by
kbuild while running "make" command. Sometimes, there is
a race condition that causes the file not created and makes
make command fail as follows:

cat: ...//modules.order: No such file or directory

This patch creates an empty modules.order file to avoid
the error.
