Add uid field to SandboxApiCalled atom

Uid field will be used to collect client app uid that makes calls to the
sandbox and be able to differentiate API calls from different apps.

Bug: 247107418
Test: manual, by running statsd_testdrive and checking that uid field
appears and is showing correct uid (works only in combination with
SdkSandboxManagerService changes)
