qemu-options.hx: Don't claim "-serial" has limit of 4 serial ports

Browse Source 
Before v2.12, the implementation of serial ports was limited to
a value of MAX_SERIAL_PORTS = 4. We now dynamically allocate
the data structures for serial ports, so this limit is no longer
present, but the documentation for the -serial options still reads:

 "This option can be used several times to simulate up to 4 serial ports."

Update to "This option can be used several times to simulate
multiple serial ports." to avoid misleading.
