Peter Krempa f536b0dd73 tests: deterministichash: Make hash tables arch-independent
It turns out that our implementation of the hashing function is
endian-dependent and thus if used on various architectures the testsuite
may have different results. Work this around by mocking virHashCodeGen
to something which does not use bit operations instead of just setting a
deterministic seed.
