osd/dmclock/testing: reorganize testing, building now optional

Modify cmake files to take advantage or re-organization of dmclock's
cmake set-up, specifically not having dmclock's cmake files call
add_test. Remove dmclock tests from being dependencies on ceph's
"test" target. Make change so dmclock tests are not built unless
WITH_TESTS and WITH_DMCLOCK_TESTS are both set. This is so openSUSE
Leap will build correctly.

crc32c: include acconfig.h to fix ceph_crc32c_aarch64()

HAVE_ARMV8_CRC is defined by "acconfig.h". so we need to include it for
the definition.

it's a regresssion introduced by 2a3382f. in that change,
crc32c_intel_baseline.h was removed from crc32.cc, and that header
includes accconfig.h indirectly. that's why we will have a dummy
ceph_crc32c_aarch64() which always returns 0. the dummy implementation
was intended to please the compiler. but we can probably just drop it in
future as a cleanup.
