CL https://codereview.chromium.org/1753993002 landed changes to allow
recover.c to compile outside of SQLite core.  It also neglected to
fully update the patches, so that patching according to
README.chromium resulted in something different from trunk.  Bring it
back in line with trunk.

Additionally update README.chromium with the current version, and
tweak the patch instructions to work better.
