stop tqdm module from creating daemon threads when instantiated with disable = False

[mike-hunhoff]

The following code snippets create daemon threads, which results in unnecessary, long running threads when calling this code from the IDA Pro plugin:

https://github.com/fireeye/capa/blob/bb7001f5f2ec02a28ed706435aea1d7e71291e8f/capa/main.py#L369

and

https://github.com/fireeye/capa/blob/bb7001f5f2ec02a28ed706435aea1d7e71291e8f/capa/main.py#L118

tqdm when instantiated creates a new daemon thread and unfortunately setting disable to False does not prevent this thread from being created, as one would expect.

For now we can manually set monitor_interval to 0 for the instantiated tqdm object when the intention is to disable tqdm progress altogether e.g.

https://github.com/fireeye/capa/blob/bb7001f5f2ec02a28ed706435aea1d7e71291e8f/capa/ida/plugin/form.py#L531-L533

yikes, that's annoying!

what if we assign tqdm.tqdm to a local variable pbar, and if the progress bar is disabled, overwrite pbar with a fake constructor, like:

pbar = tqdm.tqdm
if disable_progress:
    pbar = lambda s, *args, **kwargs: s

for f in pbar(list(extractor.get_functions()), desc="matching", unit=" functions"):
    ...

that works for me!
