Convert ioshark to Soong

Convert ioshark to Soong

See build/soong/README.md for more information.

Some modules are no longer installed by default on eng/debug builds, but
I didn't see any automatic references to them. If they're commonly used
by users, they can be added into build/make with PRODUCT_PACKAGES_ENG /
PRODUCT_PACKAGES_DEBUG. Otherwise everyone's compiles get a little
smaller.

Some modules also moved from /system/xbin to /system/bin, as we've
deprecated xbin. I checked codesearch for references to the full paths
and couldn't find any.

Test: cd system/extras/ioshark; mma
Test: for the modules changing locations, check cs/ for references
