load bundled profiles without having to use 'profile create' or '--init'

This lets `ipython profile=math` etc. behave as expected on first use.
*only* bundled config files, and not generated ones will be staged in this way.

Extra tweak: ProfileDir.copy_config_file returns True on copy, False on no-op.
