…t installed.

I was doing some debugging with PYENV_DEBUG=1 and noticed that a lot of
work was being done in conda.bash, even though I had not installed any
conda versions like `mambaforge`.

The solution is pretty simple, put all the code inside an if-block.
This aligns with what @varikin found in his pull request #3037

Additionally, I have refactored the code slightly for readability
(created function `build_conda_exclusion_list`), and added comments
which should make it easier to understand what's going on.

This commit simplifies debugging and should reduce the execution time of

```bash
eval "$(pyenv init -)"
```

slightly.

Applies to the conda blacklist in `pyenv.d/rehash/conda.d/default.list`
No practical difference, but it looks misplaced when it sits at the end
of the file.

1) Got rid of useless call to `cat`, much better to simply use sed with
   file as argument.

2) Got rid of `sort -u`. There is no need to sort the list.
   Additionally, the list `pyenv.d/rehash/conda.d/default.list` only has
   unique entries, and even if you have duplicate entries, the function
   will still work. --> No need for sort nor unique.

3) Further improvement is simple, save a cached
cleaned-list-v1.0 in `conda.d` and simple read from that file instead of
doing `sed`, which must be a more expensive operation than simply
reading from file.

Do not execute conda-specific code if conda is not installed
