sabayondevkit-functions.sh: fix typo

Package_deps returned the target package in the output which is not
strictly true (the package is not a dependency of itself really).
In calcuate_missing also means we install the package once using entropy
(if available), and then immediately replace it with portage,
which just wastes effort.

It breaks installation in the cases where the older equo version blocks the
new portage version (e.g. change of slot).

This should remove the target package from the list of packages to be
installed with entropy.
