[lldb][NFC] Remove 'from __future__ import print_function' from all tests that don't actually call 'print()'

Summary:
A lot of tests do this trick but the vast majority of them don't even call `print()`.

Most of this patch was generated by a script that just looks at all the files and deletes the line if there is no `print (` or `print(` anywhere else in the file.
I checked the remaining tests manually and deleted the import if we never call print (but instead do stuff like `expr print(...)` and similar false-positives).
I also corrected the additional empty lines after the import in the files that I manually edited.
