chore: bump version to 4.4.25 and fix CGO_CFLAGS for cross-compilation

Update version to 4.4.25 in version.txt and pkg/obioptions/version.go.

Fix CGO_CFLAGS in release.yml by replacing generic '-I/usr/include' with architecture-specific paths (x86_64-linux-gnu and aarch64-linux-gnu) to ensure correct header inclusion during cross-compilation on Linux.
