David Laight 500db21917 lib: add tests for mul_u64_u64_div_u64_roundup() ...

Replicate the existing mul_u64_u64_div_u64() test cases with round up. 
Update the shell script that verifies the table, remove the comment
markers so that it can be directly pasted into a shell.

Rename the divisor from 'c' to 'd' to match mul_u64_add_u64_div_u64().

It any tests fail then fail the module load with -EINVAL.
