another monitor.exp change

[Mark Salter <msalter@redhat.com>]

Here's another simple patch to monitor.exp which allows me to run the
testsuites on a very slow remote target. I have to work with a fixed baud
rate serial line which is overrun by the download packets, so I added
gdb_download_size which if defined will be used to set download-write-size.
Also, this hardware is slooow. It takes ~50 minutes to download a 40KB
application. So, I added a gdb_load_timeout to override the default 26 minute
timeout on loads.
