Python bindings for libemu hardcodes rpath

[xambroz]

Hello,
Python bindings for libemu hardcodes rpath - this could have some negative consequences as is therefore forbidden in many distributions as it is believed that dynamic linker and system configuration does better and cleaner job rather than hardcoding the library path to binary.

Pull request #2 is implementing the patch which has been in the past used by Debian and will be hopefully used by Fedora to remove the hardcoded rpath from the python binding.

Best regards
