gnu: hurd: Ensure startup scripts refer to the right programs.

* gnu/packages/hurd.scm (hurd)[arguments]: In 'set-file-names' phase, patch
startup.c, init.c, login.c, and daemons/runsystem/*.  Add
'patch-libexec-shebangs' phase.  Subtitute /libexec and /sbin, so that we may
run RC.
[inputs]: Add BASH-MINIMAL, COREUTILS, SED, GREP, and UTIL-LINUX.
