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

Browse Source 
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.
