webos-image: luna-sysservice=6 sntp=v4.2.6p5 ntp=0 ntp-tickadj=0

:Release Notes:
Add runtime dependency on sntp package from the existing ntp v4.2.6p5
component (whose version is now specified in
webos-preferred-versions.inc). With this submission, luna-syservice
uses sntp instead of ntpdate to support time get/set based on NTP.

:Detailed Notes:
luna-sysservice:
eb716d1 getNTPTime() doesn't work [use sntp instead of ntpdate]

:Testing Performed:
MiniBAT test. Feature test described by the next instruction:
$ luna-send -n 1 -f luna://com.palm.systemservice/time/getNTPTime '{}'

Expected result:
{
    "subscribed": false,
    "returnValue": true,
    "utc": 1372746542 // utc time must have value, not 0
}

:QA Notes:

:Issues Addressed:
[GF-10551] getNTPTime() doesn't work
[GF-13349] CCC: luna-sysservice=6 sntp=v4.2.6p5 ntp=0 ntp-tickadj=0
