pgsql: Fix another portability issue in pg_basebackup.

Fix another portability issue in pg_basebackup.

The target of sscanf with a %o format had better be of integer width,
but "mode_t" conceivably isn't that.  Another compiler warning seen
only on some platforms; this one I think is potentially a real bug
and not just a warning.
