all: remove explicit versions in USES=python for "3.x+"

The logic in USES=python will automatically convert this to 3.8+ by
itself.

Adjust two ports that only had Python 3.7 mentioned but build fine
on Python 3.8 too.

finance/quickfix: mark BROKEN with PYTHON

devel/libcdada: fix build by adding libtool to USES

devel/libcdada: new port in prepartion for net-mgmt/pmacct update

Small library that offers basic data structures (list, set, map...)
in a pure C API for user-space applications. Key features:

- Easy to use, portable
- No "magic" MACROs, and no need to modify your data structures
  (except, perhaps, for __attribute__((packed)))
- Stable and well-tested backend engine (libstdc++) for most of
  the data structures
- Reasonable performance - comparable to libstdc++
