sandbox: fix return type of os_filesize()

Browse source 
Given a file ../img of size 4294967296 with GPT partition table and
partitions:

=> host bind 0 ../img
=> part list host 0
Disk host-0.blk not ready

The cause is os_filesize() returning int. File sizes must use off_t.

Correct all uses of os_filesize() too.
