devtool.py: track to clean devtool.conf in test_create_workspace

`devtool create-workspace' would create devtool.conf, so track to
clean it up. Otherwise, this devtool.conf file would mess things up.

e.g.
oe-selftest -r devtool && oe-selftest -r devtool -j 2
AssertionError: '/PROJ_DIR/build-selftest-st-15753/workspace/conf/layer.conf' does not exist : Workspace directory not created

This is because the devtool.conf is also copied to build-selftest-st-xxxx
directory, resulting in devtool to create and use workspace specified
in this file.
