Increase the buffer size allocated to the "small" buffer.

With a ratio of 1/32 of the total buffer size traces were reporting
that the "small" buffer was not large enough. Increasing the ratio
to 1/8 seems to help.

Bug: 370730027
Test: Take some traces and check traced_buf_bytes_overwritten[1]
      in the "Info and stats" report after loading the trace.
