Add python-setuptools as Requires in specfile

[http://heffer.id.fedoraproject.org/]

python-setuptools needs to be added as Requires in the specfile. Otherwise morituri might fail with the following error:

[felix@triton Rips]$ rip cd -d /dev/sr1 rip -o 48

(In [408]) * morituri.spec.in:

Add requires for python-setuptools since we use parse_version.
Fixes #32.
