[PATCH] distutils/distutils3: Fix bashism

[Richard Purdie <richard.purdie@linuxfoundation.org>]

read -d is a bashism. Replace with a direct exec to avoid the problem
in this case. This fixes silent build failures in do_install of
tasks on systems with dash as /bin/sh.

Also merge the fix to distutils for only changing necessary files
to disutils3 as well.
