BRIN: mask BRIN_EVACUATE_PAGE for WAL consistency checking

That bit is unlogged and therefore it's wrong to consider it in WAL page
comparison.

Add a test that tickles the case, as branch testing technology allows.

This has been a problem ever since wal consistency checking was
introduced (commit a507b86900f6 for pg10), so backpatch to all supported
branches.
