Update header guards in files in velox/external/date to avoid collisi…

…on (facebookincubator#10269)

Summary:
Pull Request resolved: facebookincubator#10269

Update header guards, such as DATE_H, to VELOX_ prefixed ones,
such as VELOX_DATE_H. This is needed to avoid collision if there are
targets that include velox_external_date and the original date library
simultaneously.

This is needed for merging facebookincubator#9781.
