- Update to sysvinit 2.96
* Added -z command line paramter to pidof which tells pidof to
try to find processes in uninterruptable (D) or zombie (Z) states.
This can cause pidof to hang, but produces a more complete process
list.
* Reformatted init code to make if/while logic more clear.
* Make sure src/Makefile cleans up all executable files
when parent Makefile calls "make clean".

- Update to killproc 2.23
* killproc has its upstream at https://github.com/bitstreamout/killproc
* Use new system call statx(2) to replace old stat(2)/lstat(2)
- Remove patches now upstream:
* killproc-2.18-open_flags.dif
* killproc-2.21.dif
* killproc-sysmacros.patch
* killproc-mntinf-optional.patch
