Subject: [PATCH] bindings: python: fix library loading

On Linux the find_library() function requires ld, gcc, objdump
or ldconfig on the target, which might not be present on a
buildroot system. [1]
We do not actually need this function at all, as we know the iio library
will be referencable in the system under the name "libiio.so".
So instead of kicking of this complicated cross-platform/cross-distro
compatible machinery, we just pass in the name of the library we already
know.

[1] https://docs.python.org/3/library/ctypes.html#finding-shared-libraries

Upstream: N/A, buildroot doesn't have to care about different OS's and
distro setups, so we can just hardcode the lib name, but we cannot
submit that upstream.
