[PATCH] selftests: Add install, generate tar, and run_kselftest tools

[Shuah Khan]

kselftest_install.sh tool adds support for installing selftests
at user specified location/kselftest. By default this tool
will install selftests in the selftests/kselftest directory.
For example, kselftest_install /tmp will install tests under
/tmp/kselftest

gen_kselftest_tar.sh tool will generate user specified type of
tar archive. Default is .gz

run_kselftest.sh runs all installed selftests.
