Tom Cherry 283c9a1c00 logd: remove SocketClient from LogBuffer and LogBufferElement
In the future, we'll want to be able to write to outputs that are not
necessarily a libsysutils SocketClient, for example host tests of
LogBuffer.  Therefore, we add a LogWriter class to be used instead of
SocketClient.

Test: logging unit tests
