[lldb] Flags for running Shell tests remotely on "lldb-remote-linux-ubuntu" builder (#270)

dotest.py flags are replaced with CMake flags introduced in
llvm/llvm-project#95986 to run Shell tests
remotely.

Also, USE_LLVM_TOOLS is removed since it's implied by default that LLVM
tools will be used for API tests since
llvm/llvm-project#109961.
