Temporarily disable libsmbclient due to upstream bug

ffmpeg fails to compile with the newly released smbclient 4.9[1].
Currently, there is a pull request[2] at upstream samba that
aparently fixes this, but it still was not accepted at the time
of writing. It is being discussed on the samba mailing list[3].
Disabling libsmbclient until there is a consistent upstream
solution.
