netmetr: add python3-setuptools dependency
If I have just python3-base, python3-light and python3-pyserial packages with dependencies from netmetr and want to run python3 /usr/bin/netmetr
it throws me this traceback:
root@turris:~# python3 /usr/bin/netmetr
Traceback (most recent call last):
File "/usr/bin/netmetr", line 6, in <module>
from pkg_resources import load_entry_point
ImportError: cannot import name 'load_entry_point' from 'pkg_resources' (unknown location)
Adding python3-setuptools is enough, but setuptools install a lot of other packages. See https://github.com/openwrt/packages/pull/9224#discussion_r295031885 but I think a lot of our packages depends on setuptools, so it's fine to use that.
Compile and run tested: Turris MOX, branch: master
