gitk: include y coord in recorded sash position

6cd8049 ("gitk: Resize panes correctly when reducing window size",
2020-10-03) introduces a mechanism to record previously-set sash
positions to make sure that correct values are used while computing
resize proportions. However, if we are not using ttk, then sash
represents only the x coordinate and the recorded sash (`oldsash`) only
includes the x coordinate. When we need to access the y coordinate via
the recorded sash position, we generate the following Application Error
popup:

Error: expected integer but got ""

expected integer but got ""

expected integer but got ""

     while executing

"$win sash place 0 $sash0 [lindex $s0 1]"

     (procedure "resizeclistpanes" line 38)

     invoked from within

"resizeclistpanes .tf.histframe.pwclist 2818"

     (command bound to event)

To fix this, if we are not using ttk, we append the sash positions with
the y coordinates before recording them to match the use_ttk case.
