maint.mk: give full control over update-copyright exclusions

* top/maint.mk (VC_LIST_EXCEPT): Instead of ChangeLog, use
${VC_LIST_EXCEPT_DEFAULT-ChangeLog} as the default exclusion.
(update-copyright): Don't force inclusion of top-level
ChangeLog.  Don't force exclusion of all COPYING files, but make
them the default exclusion instead.
