Data traffic details: use proper string for System UID

Android System ≠ Android OS (second is a "kernel" process).
Mind the numbers:
http://goo.gl/YnFvHa (actual "system" process)
http://goo.gl/XwoISO ("system" process displayed as "kernel")
http://goo.gl/sJ9yMi ("kernel" process with different traffic data)

Depends on http://review.cyanogenmod.org/63190

Display BTH connected status correctly

This patch removes incorrect condition.
(to not use LocalBluetoothProfile#isPreferred())
This condition uses the priority that already disconnected profile,
so this codition always returns false.

To verify this issue:
1. Turn on Bluetooth.
2. Pair and connect to BTH(A2DP/HFP)
3. The display now says "Connected"
3. Disconnect HFP profile
4. The display still says "Connected" but it should say "Connected (no phone)"
