Speed up mac tests using various strategies (#10419)

Alternative to https://github.com/certbot/certbot/pull/10408/ and
https://github.com/certbot/certbot/pull/10415/ that fixes production
code for account meta and puts autouse fixtures in certbot and acme
tests. Overrides all `time.sleep` calls while we're at it.

Fixes the production code where it's simple/clean, and fixes the tests
for HTTPServer-based code because we just don't have that many mac users
using standalone.
