[PATCH] android/client: Fix build for android 4.3

[Jerzy Kasenberg <jerzy.kasenberg@tieto.com>]

Chagnes in HAL interface from 4.3 to 4.4 result in build failure:

target thumb C: haltest <=
    external/bluetooth/bluez/android/client/if-gatt.c
external/bluetooth/bluez/android/client/if-gatt.c:225:1:
    error: unknown type name 'btgatt_gatt_id_t'

This patch allows to build GATT for Android 4.3 (api level 18).
---

I sent this patch to the mailing list primarily to allow people
who work on android 4.3 to be able to build GATT.
