gfapi.py: support dynamic loading of versioned libraries

Currently gfapi.py only loads libraries by filename ending in ".so".  On
an installed system without development packages, the <lib>.so filenames
are not available. ctypes.util.find_library() can be used to detect the
files dynamically.

In addition to this, also fixing some minor indention errors and package
the library into the Python site-packages path. Python applications and
libraries can now access libgfapi through 'from glusterfs import gfapi'.
