tests: further relax the number of files check in test-check-sdist.t

A previous patch bumped this number due to a different version of setuptools or
distutils or some other package that we don't control, which made it pretty
obvious that this check is not really practical. We need a better way to check
that all needed files are present in the tarball.

I have some ideas, but this patch can be applied without further waiting, and
it'll already bring the benefit of not annoying developers or contributors
while at the same time still keeping the test somewhat useful.

Setting a topic namespace alone doesn't affect wdir()

  $ hg debug-topic-namespace space-name
  marked working directory as topic namespace: space-name
  $ hg debug-topic-namespaces
  space-name
  $ cat .hg/topic-namespace
  space-name

  $ hg log -r 'wdir()' -T '{topic_namespace}\n'
  none

  $ hg log -r 'wdir()' -T '{fqbn}\n'
  default

But after setting a topic the already-set namespace is visible on wdir()

  $ hg topic feature
  marked working directory as topic: feature
  $ hg topics
   * feature (0 changesets)

  $ hg log -r 'wdir()' -T '{topic_namespace}\n'
  space-name

  $ hg log -r 'wdir()' -T '{fqbn}\n'
  default//space-name/feature

  $ hg branch
  default//space-name/feature

Removing topic namespace file if it contains the default value

The default value changed from b'default' to b'none' in 11.1.0, this is a
safeguard against accidentally putting the new default tns value into commit
extras with an old version of topic extension

  $ printf 'none' > .hg/topic-namespace
  $ test -f .hg/topic-namespace
  $ hg ci -m ''
  nothing changed

  $ test -f .hg/topic-namespace

Updating to a revision with a namespace should activate it

  $ hg branch

  $ hg debug-topic-namespace

  $ test -f .hg/topic-namespace

  $ hg topics

  $ test -f .hg/topic

  $ hg up 0
  switching to topic-namespace alice
  switching to topic feature

  $ hg debug-topic-namespace

  $ cat .hg/topic-namespace

  $ hg topics

  $ cat .hg/topic

Updating to a topic namespace is not supported

Parsing

  $ hg debugparsefqbn foo/bar//user26/feature -T '[{branch}] <{topic_namespace}> ({topic})\n'
  [foo/bar] <user26> (feature)

no double slashes means it's a named branch
  $ hg debug-parse-fqbn foo/bar
  branch:    foo/bar
  namespace: none
  topic:     

Formatting

  $ hg debugformatfqbn -b branch -n namespace -t topic
  branch//namespace/topic

  $ hg debug-format-fqbn -n namespace
  //namespace/

  $ hg debug-format-fqbn -b foo/bar -n user26 -t feature
