Subject: [BUGFIX PATCH] selftests: Use real temporary working directory for archiving

Use real temporary working directory for generating kselftest
archive.

tools/testing/selftests/kselftest directory has been used for
the temporary working directory for making a tar archive from
gen_kselftest_tar.sh, and it removes the directory for cleanup.

However, since the kselftest directory became a part of the
repository, it must not be used as a working dir.

Introduce mktemp to prepare a temporary working directory
for archiving kselftests.
