software/ors-amarisoft: Fix pythonwitheggs to explicitly specify in-SlapOS lxml
Our python interpreter uses ncclient which depends on lxml egg, but does not explicitly specify to use that lxml from slapos component.
Until now we were lucky because slapos-cookbook depends on the correct lxml and
we have slapos-cookbook as the second entry in the part list with only
template preceding it.
However I needed to use pythonwitheggs inside that template and then got the build failure, because now pythonwitheggs was built before slapos-cookbook and tried to use lxml without slapos component:
