python: Fixup python binding for virDomain{Set, Get}BlockIoTune APIs

The parameter 'params' is useless for virDomainGetBlockIoTune API, and the 
return value should be a string not integer. In addition, the parameter
number is also incorrect in libvirt_virDomain{Set, Get}BlockIoTune APIs.

* libvirt-override-api.xml: Remove useless the parameter 'params' from virDomainGetBlockIoTune
API, and change return value type from integer to string.

* python/libvirt-override.c: Fix the parameter number match issue.
