firehose: Increase image write timeout to 60 seconds

The somewhat arbitrary timeout of 30 seconds was chosen by observing a
worst case time of ~15 seconds when flashing Hamoa and Nord. But, as
reported, flashing SAIL on Nord sometimes needs this timeout to be ~35
seconds.

While the relationship between the different factors and the needed
timeout isn't fully understood, bump the value to 60 seconds to make it
work for this case as well.
