Subject: player: print config.h contents in verbose mode

It was requested that mpv should print what features etc. have been
enabled at compile time. It can print the configure command line, but it
obviously doesn't include autodetected features.

I tried to think of a nicer way than dumping the config.h as text, but
this was still the simplest way.
