description:
Add new test dummy2 in lib/libpthread_dbg/t_dummy

This tests implements:
 - .proc_read with memcpy(3)
 - .proc_write with memcpy(3)
 - .proc_lookup with dlopen(3) and dlsym(3) combination

td_open() is verified to return with success (TD_ERR_OK), followed by a
call to td_close().

This test does nothing else than initializing and deinitializing td_proc_t
structure, with appropriately implemented functions.
