Remove language extention from remaining binaries.
The install target install some binaries without language extentions and others with such extension: * grgsm_capture.py * grgsm_channelize.py * grgsm_decode * grgsm_livemon * grgsm_scanner It would be more consistent and according to the policy of Debian and Ubuntu if all the binaries were without such language extention. This commit rename grgsm_capture.py and grgsm_channelize.py to avoid the language extention.
