Removed all badge links as out of date

Since waffle.io has shut down in 2019, the broken badge and its link

All three are effectively dead. In particular:
 - the ML has disappeared with the update to HyperKitty
 - Freenode has imploded - channel has not moved to Libera/OFTC
 - Slack is a ghost town - last two maintainers are not even on it

We moved libva from github/01org to github/intel, however some files
still have links to the old 01org URLs, this commit updates these links
to the new intel URLs. In addition, this commit added a contact email
address for security issue reporting

This fixes https://github.com/intel/libva/issues/189
