Subject: [PATCH] [lldb][test] skip Lua tests when the Lua interpreter is not
 found

When Swig is installed but not any Lua interpreter, the cmake script in
`lldb/cmake/modules/FindLuaAndSwig.cmake` will execute
`find_program(LUA_EXECUTABLE, ...)` and this will set the `LUA_EXECUTABLE`
variable to `LUA_EXECUTABLE-NOTFOUND`.

Ensure that in this case we are skipping the Lua tests requiring the
interpreter and the `LUAANDSWIG_FOUND` is not set.
