[Buildroot] [PATCH next 1/1] package/janus-gateway: add an option to remove the HTML demos

[Nicolas Cavallari]

janus-gateway comes with an example website to test its features.
Since the bump to 0.10.3, this website takes 1.8MiB uncompressed on the
target, among which is a 1MiB video sample which does not compress
well.

This adds an default-y option to keep the website after installation.
If unset, the website is manually deleted from the target as there is
no configure option to not install it.

Not to mention that the video is said to have been downloaded from
www2.iis.fraunhofer.de, but its terms and conditions do not seems to
allow redistribution:
