ZTS: Use decimal values when setting tunables

[behlendorf]

Motivation and Context

Failures observed when running these test cases on a non-Linux
platform using mdb.

Description

The mdb_set_uint32 function requires that the values passed in be
decimal. This was overlooked initially because the matching Linux
function accepts both decimal and hexadecimal values.
