Offer to exclude Zygote when converting heaps.

Dumps from Android devices have multiple heaps, including Zygote,
image, etc.  When investigating RAM usage, it's most useful to focus
on "real" allocations from the app, ignoring the other heaps.

This change introduces the "-z" flag which will drop allocations
on non-app heaps during conversion.
