Fix filedescriptor out of range in select() when running commands (#65058)
* Fix filedescriptor out of range in select() when running commands

* Simplify the run_command() code

Now that we're using selectors in run_command(), we can simplify some of
the code.

* Use fileobj.read() instead of os.read()
* No longer use get_buffer_size() as we can just slurp all of the data
  instead.

Also use a simpler conditional check of whether the selector map is
empty
