tests/migration: Reduce autoconverge initial bandwidth
When using max-bandwidth=~100Mb/s, this test fails on Travis-CI
s390x when configured with --disable-tcg:
$ make check-qtest
TEST check-qtest-s390x: tests/qtest/boot-serial-test
qemu-system-s390x: -accel tcg: invalid accelerator tcg

Per David Gilbert, "it could just be the writing is slow on s390
and the migration thread fast; in which case the autocomplete
wouldn't be needed. Perhaps we just need to reduce the bandwidth
limit."
Tuning the threshold by reducing the initial bandwidth makes the
autoconverge test pass.
