script/run-cbt.sh: set fs.aio-max-nr for seastar

seastar requires 11027 for each reactor, so we need at least

fs.aio-max-nr = 11027 * n_osd

but to make it simple and to take the needs of other applications using
aio on the machine, we increase the number of io context to 32768,
and always set this setting no matter if we are starting a vstart
cluster with classic osd or crimson osd
