从test result以及logcat看测试失败的原因是：没有 access Media / DrmManager的权限
发现log中的avc信息：

07-23 23:38:37.483   296   296 E SELinux : avc:  denied  { find } for service=drm.drmManager pid=6532 uid=10185 scontext=u:r:ephemeral_app:s0:c512,c768 tcontext=u:object_r:drmserver_service:s0 tclass=service_manager permissive=0

那我们测试此项gts前执行 adb shell setenforce 0, 然后执行gts命令：run gts -m GtsPackageManagerHostTestCases -le.s.PackageManagerHostTest#testSoundPool，结果是pass.可以确定原因，需要添加权限，根据avc log，需添加如下信息到中：
allow ephemeral_app drmserver_service:service_manager { find };
完成添加编译版本测试OK
