[lldb-dap] Adjust the evaluate test to use a different lldb command. (llvm#116045)

Previously this used `var` as both an lldb command and variable in the
source to validate the behavior of the 'auto' repl mode. However, `var`
seems to occasionally fail in the CI test when attempting to print some
c++ types. Instead switch the command and variable name to `list` which
should not run the dynamic variable formatting code for c++ objects.

This should fix llvm#116041.

(cherry picked from commit c658d07)
