Proposed patch

When XMPP calls with empathy outgoing audio calls fail due to nicesink failing to be linked to the rtp muxer as it returns EMPTY when querying caps as it tries to give the result of intersecting incompatible caps (dtmfsrc & the audio stream)

Looks good, also it should probably go into the 1.4 branch

    rtpmux: Don't set PROXY_CAPS flag on the src pad
    
    rtpmux behaves like a funnel in that it forwards whatever upstream is
    sending buffers. So setting proxy caps doesn't make sense as the
    upstream don't have to have compatible caps, thus resulting in an empty
    caps set as a result of a caps query. Instead set fixed caps just
    as funnel does.

Cherry-picked into 1.4 branch as well.
