Use cmake TIMESTAMP function

Browse Source 
Summary:
because it is not only platform independent
but also allows to override the build date
This helps to make ceph builds reproducible (that includes a fork of rockdb in a submodule)

Also adds UTC flag, to be independent of timezone.

Requires cmake-2.8.11+ from 2013
Closes https://github.com/facebook/rocksdb/pull/2848

Differential Revision: D5820189
