CodingStyleTest: do not install erp5_upgrader test dependencies and full text

We were installing erp5_upgrader with its test dependencies, so it was
installing erp5_full_text_mroonga_catalog. We were also installing
erp5_full_text_myisam_catalog, so we ended up with two full text
business template installed (and the order of this installation was not
deterministic).
This was problematic, because we were installing all the test dependencies
of erp5_upgrader, but we don't really need them here and one goal of
CodingStyleTest is to install only the dependencies of tested business
templates, as a way to verify that dependencies are correctly specified.

This new approach hooks at another level, to install a full text business
template only if the tested business template has a dependency to the
virutal "erp5_full_text_catalog" bt, but no depencency to a concrete bt
(which happens for example in erp5_base) and to install erp5_upgrader
without its test dependencies.

This also reverts commit ab44309f (
full_text_myisam_catalog: skip coding style test) that is no longer
needed with this new approach.
