These changes are mostly to help cleanup issues in HaikuPorter's
repo_consistency.txt report: some build-requires chains broken due to
`cmd:python` (2.x) not being available anymore.
libxcb build was failing due to import errors in xcb_proto (due to changes
in Python 3.5+), resolved in newer xcb_proto, which prompted the libxcb update
to keep them in sync.

While libxcb should not be needed in Haiku, some ported software (eg: `libfm_qt`)
depends at least at build time on it. Until those get patched to not require
libxcb... we're stuck with this.

Due to bogus python version detection (expecting "Python 2.x"),
current package is installing files under:
/system/lib/python/po/vendor-packages
instead of
/system/lib/python3.xx/vendor-packages
This is just a quick fix for that.
* Referring the current haiku version explicitly is not needed, since
the RequiresUpdater takes care of setting the version of Haiku used
for building a package.
* this fixes the wrong recipe names introduced by myself in #d525fee
* adjust patch names to match corresponding recipes
* additionally: create 'additional-files' folders as hint to some
ports that do not have a proper recipe yet
