Subject: gnu: python-uvloop: Update to 0.16.0.

Version 0.14.0 is not compatible with Python 3.9[1]. Additionally unvendor the
copy of libuv, which was unused, but retained in the source tarball,
fix subprocess spawning and enable tests, so we know when future updates
break it.

[1] https://github.com/MagicStack/uvloop/issues/349

* gnu/packages/python-web.scm (python-uvloop): Update to 0.16.0.
[source]: Add snippet to remove pre-built loop.c and vendored libuv.
[arguments]<#:phases>: Substitute /bin/sh in 'preparations phase, override
'check phase and disable failing tests.
[native-inputs]: Remove python-flake8, because it causes test failures
and add python-pytest-timeout.
