storage: Support a default virtual sector size

Browse source 
Normally, we figure out the virual sector size from the filesystem info.
However, if there's no filesystem, we fall back to the hardware's
logical sector size.

Some device firmware (eg ipod5g/6g) need their partition tables set up
with larger-than-logical sector sizes; this way we can present the
"correct" sector size to maintain interoperability with the stock
firmware and make it so that the drive can still be properly partitioned
from within rockbox.

This patch adds support for DEFAULT_VIRT_SECTOR_SIZE.  Nothing uses it yet.
