Uh oh!

Add a new ProfileCLITest class to Lib/test/test_profile.py with tests covering the full CLI surface of the profile module:
- No arguments prints usage and exits with code 2
-h/--help prints usage and exits with code 0
- Profiling a script file directly
-m flag to profile a library module
-m flag with a non-existent module (failure case)
-o/--outfile writes a valid pstats file
-s/--sort accepts a sort key without error
-m alone without a module name (failure case)
Sorry, something went wrong.
