lit: Use a License classifier that pypi will accept

[tstellar]

Summary

'OSI Approved :: Apache-2.0 with LLVM exception' is not a valid
classifier. 'OSI Approved :: Apache Software License' is the closest
fit for the new license, so we've decided to use this one.

The classifiers seem to only be used for searching on the pypi website,
so this does not actually change the license of the code.
We still pass 'Apache-2.0 with LLVM exception' as the license to setup(),
and this appears alongside the classifier on the pypi webpage for lit.

[tstellar]

Remove accidental version bump.

[tstellar]

Change license classifier to: OSI Approved :: Apache Software License
as suggested by Joerg on IRC.

[tstellar]

Add missing comma.

Thanks, this looks good enough within the limitations of the framework.
