Enable check-TESTS using %check section in bluez

This patch enables check-TESTS (unit test case execution) for bluez at
build time using %check section in bluez.spec. This patch,
 - Modifies unit/test-gobex.c, unit/test-gatt.c, unit/test-hog.c and
   unit/test-gattrib.c to handle Tizen specific changes in BlueZ.
 - Disables crypto test cases (unit/test-crypto) as QEMU (v2.7.0) in
   Tizen does not support AF_ALG socket option for cypher algorithms.
