t: use hash-specific lookup tables to define test constants
In the future, we'll allow developers to run the testsuite with a hash
algorithm of their choice. To make this easier, compute the fixed
constants using test_oid. Move the constant initialization down below
the point where test-lib-functions.sh is loaded so the functions are
defined.
Note that we don't provide a value for the OID_REGEX value directly
because writing a large number of instances of "[0-9a-f]" in the
oid-info files is unwieldy and there isn't a way to compute it based on
those values. Instead, compute it based on ZERO_OID.
