trace-vmscan-postprocess: sync with tracepoints updates

The script has fallen behind tracepoint changes for a while, fix it up.

Most changes are mechanical (renames, removal of tracepoint parameters
that are not used by the script).  More notable change involves
mm_vmscan_lru_isolate which is relying on the isolate_mode to determine if
the inactive list is being scanned.  However the parameter currently only
indicates ISOLATE_UNMAPPED.  We can use the lru parameter instead to
determine which list is scanned, and stop checking isolate_mode.
