Remove NTPServers duplicate values and null values

When saving the set NTPServers values from webUI, NTPServer may contain
duplicate values and null values and update them to D-Bus.

Now, need to parse and verify the value of the ntpServers attribute,and
remove duplicate values and null values.

Tested:save NTP and check it via D-Bus
without this patch:
NTPServers  property  as  3 "" "10.164.29.2" "10.164.29.2"

with this patch:
NTPServers  property  as  2 "" "10.164.29.2"
