David Pursell 2c094f7983 fastboot: fix SocketMock send failures.
Fixes SocketMock::ExpectSendFailure() to allow unit testing of errors
during send, and adds tests for ExpectSendFailure() and
AddReceiveFailure().

Also adds missing tests to make sure ReceiveAll() continues to read
until failure or all bytes have been read.
