Fix determination of broken LSN in OVERWRITTEN_CONTRECORD
In commit ff9f111bce24 I mixed up inconsistent definitions of the LSN of
the first record in a page, when the previous record ends exactly at the
page boundary. The correct LSN is adjusted to skip the WAL page header;
I failed to use that when setting XLogReaderState->overwrittenRecPtr,
so at WAL replay time VerifyOverwriteContrecord would refuse to let
replay continue past that record.
Backpatch to 10. 9.6 also contains this bug, but it's no longer being
maintained.
