Update DR to latest to fix elfutils issue (#2542)

Updates DR to the latest a09c4c9f5a0503aaa4efc2c9d59aada92de85291 to
pull in the fix for DynamoRIO/dynamorio#7253 to avoid submodule issues
with elfutils from sourceware.org.

Updates the toolchain-android.cmake paths for the recent renaming in DR.
