I think you need to add the following to the make-music section of the
make-tremolo function:

'tremolo-type dur

I'm not sure when this was changed, but this made it work in 2.15.19.
I haven't looked at this in depth so there could be other issues.

For future reference, the way I debugged this was to compare the
output of \displayMusic of the standard \repeat tremolo ...  what the
\tremolos ... function created and noticed the missing parameter.
