Laurent Vivier 00ed8a3459 linux-user: don't use AT_EXECFD in do_openat() 
AT_EXECFD gives access to the binary file even if
it is not readable (only executable).

Moreover it can be opened with flags and mode that are not the ones
provided by do_openat() caller.

And it is not available because loader_exec() has closed it.

To avoid that, use only safe_openat() with the exec_path.
