Switch to seaweedfs/cockroachdb-parser directly

Removed the replace directive and updated all references to use
github.com/seaweedfs/cockroachdb-parser directly instead of redirecting
from github.com/cockroachdb/cockroachdb-parser.

Changes:
- Updated import in weed/query/engine/cockroach_parser.go
- Removed replace directive from go.mod
- Now using seaweedfs/cockroachdb-parser@909763b171
  which includes all 32-bit architecture fixes and uses
  seaweedfs namespace throughout

Build verified successfully for GOOS=openbsd GOARCH=arm.
