hashsum: support --check for algorithms with variable output length (#2583)

Browse source 
* hashsum: support --check for var. length outputs

Add the ability for `hashsum --check` to work with algorithms with
variable output length. Previously, the program would terminate with an
error due to constructing an invalid regular expression.
