Commit 035af998 made avconv always call an encoder when using the
null muxer.  While useful for 2-pass encodes, it inadvertently

allowing use of the null muxer with encoded streams as well.

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
