sysvinit: pidof add -m option for lsbinitscripts
When reboot the system on lsb image, some kill processes would print the following message: ... pidof: invalid options on command line! ... The killproc in lsbinitscripts invokes pidof with option -m, but the pidof in sysvinit package doesn't support this. Backport from fedora to add -m option on pidof could fix this issue.
