avcodec/srtenc: Don't copy data around unnecessarily

Using av_bprint_init_for_buffer() avoids copying data
into the internal AVBPrint buffer (or worse: to allocate
a temporary buffer in case the internal buffer does not
suffice). It also ensures that the data is always
0-terminated, whereas the current code never does this
and returns success in case the length of the
string to write and the size of the buffer coincide.
