package/python-pysensors: fix build without host lm-sensors

Fix the following build failure raised since the addition of the
package in commit c8ff8d41c06f6b1cbc5cf8702a516411084ead16:

  File "/home/buildroot/autobuild/instance-2/output-1/build/python-pysensors-0.0.4/setup.py", line 3, in <module>
    import sensors
  File "/home/buildroot/autobuild/instance-2/output-1/build/python-pysensors-0.0.4/sensors/__init__.py", line 20, in <module>
    raise ImportError("can't find the sensors library.")

Fixes:

+Remove import sensors from setup.py

+Don't import sensors in setup.py to avoid adding a dependency on host
+lm-sensors. Instead, move __version__, __author__, __contact__ and
+__license__ to setup.py
