Add a new "--no-template" convenience option to "git init" and "git
clone".
This option is functionally equivalent to the long-standing "trick" of
providing an empty parameter to --template, i.e. "--template=". See
172035f044e (init: handle empty "template" parameter, 2008-07-28).
But that long-standing trick has never been documented, and isn't
obvious. Instead of documenting it let's provide an alternate way of
doing this that conforms with how we usually handle other such cases.
Let's also add a GIT_NO_TEMPLATE_DIR environment variable. For now
this is for consistency with the existing "GIT_TEMPLATE_DIR", but in a
subsequent commit we'll make use of it within "t/test-lib.sh".
