bitbake: toaster: moved import bb.server.xmlrpc

Moved import xmlrpc module to the place where it's used
to avoid toaster crashes when importing bitbake code.

NOTE: This patch is made to be able to partly test toaster
with bitbake from master. It can be removed as soon as bb.server.xmlrpc
is ported to python 3.
