gstlal_compute_strain:  Corrected mistakes with reading EP10 from frames and casting gps-start-time to an int

- remove reference to python elements and to interleave plugin
- update name of gstreamer python bindings RPM
- don't source gstenvironment.sh in .spec
- bump minimum required gstlal and gstlal-ugly for ER9

- Included lal_constantupsample_test.py for testing, updated test_common.py in gstlal-calibration to match what is in gstlal.
