Tests: Remove some unused member variables.

Fix warnings:

tst_qtcpsocket.cpp:245:9: warning: private field 'numConnections' is not used [-Wunused-private-field]
    int numConnections;
        ^
tst_qtcpsocket.cpp:1834:9: warning: private field 'exitCode' is not used [-Wunused-private-field]
    int exitCode;

tst_qcheckbox.cpp:86:10: warning: private field 'tmp' is not used [-Wunused-private-field]
    uint tmp;
         ^
tst_qcheckbox.cpp:88:10: warning: private field 'tmp2' is not used [-Wunused-private-field]
    uint tmp2;

Below warning is caused by code #ifdefed for OS X only, make it a local variable:
tst_qlabel.cpp:114:16: warning: private field 'test_edit' is not used [-Wunused-private-field]
    QLineEdit *test_edit;
