enlightenment.enlightenment: no need to fix edje_cc path

Upstream looks for the edje_cc binary (which is provided by efl) in
the bin subdirectory of the enlightenment package prefix. If not found
it is called without giving a directory (that is, it defaults to
$PATH). Therefore a fix is not needed anymore.
