Fix the SETF expander to work with APPLY for arbitrary function

[Mark Evenson]

CL-CONTAINERS from Quicklist MAR2011 fails to compile because our SETF expander for APPLY doesn't work for functions other than #'AREF, #'BIT, and #'SBIT as can be seen by the ERROR generated by late-setf.lisp​.

The SETF expansion for APPLY should work with an arbitrary function.

(In [13450]) Fix #141 (SETF of APPLY not working with arbitrary function) by
"adding" the feature.
