avformat: allow .ec3 as extension for raw E-AC-3 stream

In addition to .eac3, .ec3 is also commonly used by people to name raw E-AC-3 streams. Enables automatic recognition of the eac3 format for the .ac3 extension. For instance Dolby Digital Plus software only support files with .ec3. Files with .eac3 are not supported. Check issue #18 in the public dlb_mp4base repository from DolbyLaboratories.
