AU: When applying delta locally, get source checksums

When applying a delta on the host, we need to calculate the original
checksums for the rootfs/kernel for the delta performer. This CL does
that.

Also:
- Log old/new checksums in performer
- Add base64 encode function to OmahaHashCalculator

BUG=8062
TEST=unittests; applied delta on host
