Subject: [PATCH 2/2] THRIFT-3831 in test/cpp explicitly use `signed char`

`char`'s signed-ness is implimentation dependent, and in the case where
`char` was not signed, we previously recieved errors like

    thrift/0.9.3-r0/git/test/cpp/src/TestClient.cpp:404:15: error: narrowing conversion of '-127' from 'int' to 'char' inside { } [-Wnarrowing]

(This example from gcc-6 on arm)
