Fix build of kcov tests on CPUs without 64-bit atomics

Browse Source 
Restrict the 64-bit atomics to ports defining __HAVE_ATOMIC64_OPS.

Using 64-bit atomics is still good for i586 fuzzing, but the tests are
build for earlier CPUs. This makes this code to be disabled in i386 builds.

There is a similar situation with few other ports that offer 64-bit atomics
in certain CPU models and ABIs.
