Handle chrome.dll.pdb properly when incremental_chrome_dll is set.

Handle chrome.dll.pdb properly when incremental_chrome_dll is set.

Also:
- speed up re-copies the XP/xcopy case by skipping old files
- clean up output for re-copies in the robocopy case by ignoring "extra" files

File tools/win/copy-installer.bat (right):

https://chromiumcodereview.appspot.com/10837096/diff/1/tools/win/copy-install...
tools/win/copy-installer.bat:110: robocopy "%FROM%" "%TO%" %TOCOPY% /J /MT /XX
I'm not clear on what /XX does, from http://ss64.org/viewtopic.php?id=1370 it
doesn't seem to do much... (and the actual documentation is even more vague).

in this case, it only suppresses meaningless output ("clean up output for
re-copies in the robocopy case by ignoring "extra" files").
