Improve aligned_alloc/calloc/malloc test coverage by adding
multi-threaded tests with random memory allocations and with/without
cross-thread memory deallocations.

Modify the existing DSO used for random memory allocations to avoid
getting global locks in the allocation process.

The new tests are added to tests-exclude-mcheck as they don't seem
to play well with mcheck and I have not been able to find any problem
with the tests themselves. Happy to fix anything and/or file an issue
in mcheck for further investigation.
