Use .KATI_RESTAT to reduce unnecessary rebuilds of .jar files

The same optimization was done for binaries in

https://android-review.googlesource.com/#/c/175250/

To create a TOC file from .jar files, this change introduces
ijar, which is designed for this purpose. Only #include lines
were modified from the original version.

Performance:

$ m && touch
frameworks/base/core/java/com/google/android/util/Procedure.java && time
m
Before: 4m30s (1580 targets)
After: 3m57s (772 targets)

Unfortunately, the improvement is small yet, but local
experiments showed we can cut ~2 more minutes if the similar
optimization is done for .dex files.
