Subject: [PATCH] simulator: Fix 64-bit offset build failures

Fix brekage from first merging commit d959319b ("Merge 'Use u64 for file
offsets in I/O and calculate such offsets in u64' from Preston Thorpe")
and then commit 6591b66c ("Merge 'Simulate I/O in memory' from Pedro
Muniz"), which was unaware of the changes.
