Fix BuildPulse handling

- be more verbose with output to be clear when we're using/submitting to
  BuildPulse
- remove the duplicate BuildPulse submission step

Doesn't work with system `curl` currently.

Replace Nokogiri with REXML

formula_auditor: don't allow `bottle :unneeded` in core.

Tweak BuildPulse/`rspec-retry` logic

BuildPulse is trying to find flaky tests for us but, given the previous
model of using `rspec-retry`, it would rarely find them. Instead, let's
try to always rerun `brew tests` multiple times, report to BuildPulse
each time (by moving the reporting logic into `brew tests`) and disable
`rspec-retry` when using BuildPulse.

While we're here, let's enable `rspec-retry` locally so we don't have
flaky tests biting maintainers/contributors there.

Now we have `all:` bottles and Bintray is going away for `mirror`s:
let's bottle everything in Homebrew/homebrew-core.

language/python: create venvs with access to system site packages

livecheck/strategy/sparkle: check minimumSystemVersion for compatibility

A user may wish to use two use two brew-installed Python packages
together. For example, one might want to `import numpy` when using
`jupyterlab` or `ptpython`.

Currently, the only ways to do this I'm aware of is with some hacking of
`PYTHONPATH` or the creation of `.pth` files in a formula's prefix.

A better solution is to allow the virtualenvs that `brew` creates to
have access to system site-packages by default, so that `import numpy`
inside `ptpython` or `jupyterlab` just works.

Partially resolves Homebrew/homebrew-core#76950.

default_prefix: set macOS default prefix on Linux if simulating it

Update maintainers, manpage and completions.

formula: capture build logs more comprehensively
