Embrace environment markers (a.k.a. PEP 508 compliance)! 

Failure to use environment markers means the dependencies are
unconditionally added at build time based on the host instead of being
always present and evaluated at runtime on the target; e.g. wheels have
the wrong information.

Also use python_requires. This teaches pip how to natively comprehend
when the current version of python is not supported by borg.

Returns errors in the format:
borgbackup requires Python '>=3.5' but the running Python is $oldver
