sysvinit: make pidof usuable in a standalone setting

sysvinit: make pidof usuable in a standalone setting

Currently it's a symlink to killall5:

$ dpkg-deb -c sysvinit-pidof_2.88dsf-r1_armv7a.ipk  | grep pidof
lrwxrwxrwx root/root         0 2011-05-27 11:05 ./bin/pidof.sysvinit -> /sbin/killall5

The point of the pidof subpackage was to have a pidof without needing sysvinit, this restores that behaviour.
