We are missing "kselftest_module.sh" file when we do "make install"
and followed by generating a tar file "gen_kselftest_tar.sh" and
copying that on to target device and running tests by using
"run_kselftest.sh" script file on the target.

Could you install the supporting script file "kselftest_module.sh" ?
