t7502: clean up fake_editor tests

Using write_script saves us a few lines of code, and means
we consistently use $SHELL_PATH.

We can also drop the setting of the $pwd variable from
$(pwd). In the first instance, there is no reason to use it
(we can just use $(pwd) directly two lines later, since we
are interpolating the here-document). In the second
instance, it is totally pointless and probably just a
cut-and-paste from the first instance.

Finally, we can use a non-interpolating here document for
the final script, which saves some quoting.
