Patch: Don't show __main__.py in program help

[forthrin]

__main__.py is shown when launching youtube-dl in alternative ways. This is somewhat unsightly.

$ alias youtube-dl='~/Downloads/youtube-dl/youtube_dl/__main__.py'
$ youtube-dl
Usage: __main__.py [OPTIONS] URL [URL...]
__main__.py: error: You must provide at least one URL.
Type youtube-dl --help to see a list of all options.

$ cd ~/Downloads/youtube-dl && python -m youtube_dl
Usage: __main__.py [OPTIONS] URL [URL...]
__main__.py: error: You must provide at least one URL.
Type youtube-dl --help to see a list of all options.

Patch:

• I've verified and I assure that I'm running youtube-dl 2019.03.09
• At least skimmed through the README, most notably the FAQ and BUGS sections
• Searched the bugtracker for similar issues including closed ones
• Checked that provided video/audio/playlist URLs (if any) are alive and playable in a browser
• Bug report (encountered problems with youtube-dl)

This is expected behavior.
