Install libnifalcon.pc file even if pkg-config executable doesn't exist

[ryandesign]

On UNIX systems, CMakeLists.txt looks for the pkg-config executable and only if it is found does it generate and install the libnifalcon.pc file. As far as I can tell you never use the pkg-config executable so there is no need to check for its existence. Just always generate and install libnifalcon.pc on UNIX.
