[packages] monit: Bump to 5.4 and bugfixes

Hi
this patch update monit from 5.2.5 to 5.4, this add cool feature like "check program", to execute a script and send email/do action depending on the return code, and many bugfixes (http://mmonit.com/monit/dist/CHANGES.txt)
I've modified the init script because "-d 60" overide the conf file and the stat command doesn't seem to exist, so either we just chmod each time or we let the people RTFM and the syslog (i prefer the latter)

For now i've tested only the ssl version with backfire (r31676) on x86 and ar71xx (tplink wr1043nd) (it send mail via google, ping, watch load average and cpu ...)
It compile (monit and monit-nossl) for x86 and ar71xx for backfire & trunk (trunk x86 mount the ext4 partition readonly so i haven't tested)
