[PATCH] android/daemon: Solves warnings when compiling for Android

[Andrei Emeltchenko <Andrei.Emeltchenko.news@gmail.com>]

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

When compiling for Android I get very annoying warnings shown below.
Though the issue is with android this really helps to clear Android
build screen.

external/bluetooth/bluez/android/main.c: In function 'cmd_watch_cb':
external/bluetooth/bluez/android/main.c:192:3: warning: format '%zd' expects
  argument of type 'signed size_t', but argument 2 has type 'ssize_t' [-Wformat]
external/bluetooth/bluez/android/main.c:197:3: warning: format '%zd' expects
  argument of type 'signed size_t', but argument 2 has type 'ssize_t' [-Wformat]

 Let me know if this solution is OK and I will change other parts as well.
