zdtm: add checksum tests

This adds 6 tests:
1. The last byte of the file is altered after dump and before restore,
causing restore to fail (checksum-full)

2. checksum, checksum-parameter = 10485800 (First 10485800 bytes are
checksummed)

3. checksum-period, checksum-parameter = 10485800 (Every 10485800th byte
is checksummed)

4. checksum, checksum-parameter = 10485700 (First 10485700 bytes are
checksummed)

5. checksum-period, checksum-parameter = 10485700 (Every 10485700th byte
is checksummed)

6. The last byte of a file of size 10485800 bytes is altered after dump
and before restore, causing restore to fail
checksum, checksum-parameter = 10485800 (First 10485800 bytes are
checksummed)
