lavf/rtpdec_g726: Map mime type G726 to g726le.

Browse Source 
Add new mime types AAL2-G726 for g726 as suggested in rfc 3551.

This patch will break interaction with applications that incorrectly
use big-endian G.726 with mime type G726 but we know of at least one
device (DVTel camera) that correctly implements the rfc, so do the same.

Fixes ticket #5890.
