vendor.prop: set ro.boot.wificountrycode=US instead of 00

Browse source 
The world regulatory domain (00) forces passive scanning on all 5GHz
channels and limits TX power to 3 dBm.  For a device whose AP is on
channel 144 (5720 MHz, DFS), this means:
  - Scans must wait for beacons instead of actively probing
  - DFS channel availability check adds up to 60s delay
  - Transmit power is crippled to 3 dBm

Setting to US enables active scanning, proper TX power, and standard
DFS handling, which eliminates the 2-3 minute connection delay.

Users in other regulatory domains should override this via their own
vendor.prop or the build system.
