Merge 'sim: ignore fsync faults' from Jussi Saurio

`FaultyQuery` causes frequent false positives in simulator due to the
following chain of events:
- we write rows and flush wal to disk
- inject fault during fsync which fails
- error is returned to caller, simulator thinks those rows dont exist
because the query failed
- we reopen the database i.e. read the WAL back to memory from disk, it
has those extra rows we think we didn't write
- assertion fails because table has more rows than simulator expected
More discussion about fsync behavior in issue #2091

Closes #2110
