only check the major versions of remote and local libiio 

If they are the same, don't error out even if the minor versions are
different since libiio should have backwards and forwards compatibility
to some extent. When backwards incompatible ABI/API changes are made,
the major version should be incremented at which point an error will be
raised when trying to connect.
