[OE-core] [PATCH 1/2] runqemu: Add the support to pass multi ports to tcpserial parameter

[Kevin Hao]

In some cases(such as the oeqa's qemurunner), we need to setup multi
serial devices via the '-serial 127.0.0.1:xx" and the order of them
is significant. The mixing use of "tcpserial" and "-serial 127.0.0.1:xx"
cause ambiguous issues and we can't fix it by only adjusting the order
of them. So add the support to pass multi ports to the tcpserial
parameter, this will make sure that the order of setting up the serial
is really what we want.
