Change the hashtree hash algorithm to sha256
Bug: 155771970
Test: build an arbitrary APEX (e.g. com.android.runtime)
$ unzip com.android.runtime.apex
$ avbtool info_image --image apex_payload.img | grep Hash
Hashtree descriptor:
Hash Block Size: 4096 bytes
Hash Algorithm: sha256
Test: compare the APEX size before and after the change: no difference
