Minor fix in SysV init for Hurd

[Jesse Smith]

I've published a minor bug fix for SysV init. This release is tagged as
version 3.04 and its only change is a small fix to make sure SysV init's
bootlogd utility compiles on GNU Hurd. Everything else is functionally
the same. So on all platform apart from Hurd version 3.03 and 3.04
should be identical.

The new release is available on GitHub:
