Fix SUB_LIST and script
This is related to bug #209799, same root cause: the removal of
kdehier and USE_KDE4=kdeprefix is a bit too thorough. Here, it
leaves us with a blank variable in SUB_LIST, which ends up in a
shell script. The substitution leaves the shell script with syntax
errors.
Since $KDE4_PREFIX must be equal to $LOCALBASE, remove the substitution
and simplify the script.
