[crc64] Change the hash prefix back to crc64 (#628)

Context: 9b88ce7
Context: 7fe3a11

7fe3a11 fixed the new CRC64 calculation algorithm so that it properly
processes all the data, which had the (expected) effect of generating
the same checksums for the same data as those generated before
commit 9b88ce7.

However, 7fe3a11 missed changing the new `c64r2` hash prefix back to
`crc64`, thus this commit to make the change.

The change will remove any backward incompatibility with code that may
rely on the old hash format, including Xamarin.Android tests.
