rgw/file: advance rgw_file interface version

The following commit changed the rgw_file.h external interface, but did
not advance the interface version.

This commit needs to follow the interface change to all backports (e.g.,
Reef).

    rgw/file: change function signature to match the one generated by cython

    without this change, clang16 fails to compile,
    due to conversion from "bool" to "int".
