disable sha-1 hashing for policy for Ubuntu Touch

[Jamie Strandboge]

Currently there is a compile time option to disable/enable sha-1 hashing of profiles. While enabling this option is useful for debugging, it can incur a 1 second cache load penalty on Ubuntu Touch with ~100 profiles. Upstream task is to make this runtime/boot time configurable.
