ffmpeg | branch: master | James Almer <jamrial at gmail.com> | Thu Oct  5 00:47:41 2017 -0300| [cafd9d66ed9e1bad4ae579a3935f7af57a567a51] | committer: James Almer

build: add install targets for the examples

Split it off from install-data.

Among other things, this prevents spamming triplicate log lines during install.
