python: bump all USE_PYTHON=distutils consumers after RUN_DEPENDS removal

Any missed ports, feel free to bump.

Any ports that need setuptools at runtime can have the devel/py-setuptools
manually added back to RUN_DEPENDS, but understand that this practice
is deprecated; see CHANGES for details.

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/py-python-bitcoinlib: Update to 0.12.0

Changelog:

* "CECKey" now rejects secrets that aren't exactly 32 bytes

* Now compatible with OpenSSL v3; broke compatibility with certain
  script edge cases around malformed signatures.  This is acceptable
  because python-bitcoinlib doesn't claim to have consensus
  compatibility and no-one should use it for script/tx validation.

*/*: rename CHEESESHOP to PYPI in MASTER_SITES

finance/py-python-bitcoinlib: Update to 0.11.2

Changelog since 0.11.0:

* Pure-python RIPEMD-160, for newer versions of OpenSSL without
  RIPEMD-160 support.
* Signet support

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

MFH:		2019Q3

New port: finance/py-python-bitcoinlib

Provides an easy interface to the bitcoin data structures and protocol. The
approach is low-level and "ground up", with a focus on providing tools to
manipulate the internals of how Bitcoin works.
