pgsql: Re-add translation markers that were lost

Re-add translation markers that were lost

When win32security.c was moved from src/backend/port/win32/security.c,
the message writing function was changed from write_stderr to log_error,
but nls.mk was not updated. We could add log_error to GETTEXT_TRIGGERS,
but it's also used in src/common/exec.c in a different way and that
would create some confusion or a larger patch. For now, just put an
explicit translation marker onto the strings that were previously
translated.
