BaseTools:Update binary cache restore time to current time

https://bugzilla.tianocore.org/show_bug.cgi?id=1742

Current Binary Cache doesn't update the restored file
creation and modification times to the current time.
Preserve the new restored file creation time as old
cached time might has potential issue to block the make
to build updated files based on the time stamp.
Enhance to update the restored file creation time to
current time.
