Change warning logic in preopt2cachename

We were incorrectly warning when a filename had 8 segments. This is
valid since we can have paths of the form
'/postinstall/product/priv-app/<app>/oat/arm64/<app>.odex' in addition
to those of the form
'/postinstall/priv-app/<app>/oat/arm64/<app>.odex'.

Test: boot, look at logcat
