Fix C++ build

[mhlakhani]

#3165 broke the build with c++11.

I split out the compile time fix from https://github.com/apache/thrift/pull/3167/files#diff-d8d7400cdf01511c2ad2df7caf958173c2e96e8633271709c9b0b5cd8e89215c to ensure we have a clean trunk (so I can have other changes on top). I can't take credit for the fixes.

I verified this compiles with gcc, clang (on c++11) and also on clang with c++1z

• Did you create an Apache Jira ticket? (Request account here, not required for trivial changes)
• If a ticket exists: Does your pull request title follow the pattern "THRIFT-NNNN: describe my issue"?
• Did you squash your changes to a single commit? (not required, but preferred)
• Did you do your best to avoid breaking changes? If one was needed, did you label the Jira ticket with "Breaking-Change"?
• If your change does not involve any code, include [skip ci] anywhere in the commit message to free up build resources.

Thanks, I am not sure what the holdup is on #3167
Nonetheless you will also need the change in "lib/cpp/src/thrift/transport/TSocketUtils.h" Same idea different file

thanks @CJCombrink ! I've pulled in those changes -- though I wasn't able to reproduce that build failure.
