hghave: move from requiring the PYTHON3 env var to looking for `python3`

We're starting to write new utility scripts in Python 3, and I think
it's reasonable to expect `python3` to be something we should use if
it's present. I wrote the regex to specifically ban Python 3 prior to
Python 3.5 because we won't ever support that.

I moved the only test that was using $PYTHON3 to just using `python3`
directly.

# An example FastCGI script for use with flup, edit as necessary

# Path to repo or hgweb config to serve (see 'hg help hgweb')
config = "/path/to/repo/or/config"

# Uncomment and adjust if Mercurial is not installed system-wide
# (consult "installed modules" path from 'hg debuginstall'):
#import sys; sys.path.insert(0, "/path/to/python/lib")

# Uncomment to send python tracebacks to the browser if an error occurs:
#import cgitb; cgitb.enable()
