[PATCH 19.11 2/4] eal: fix C++ include

[Bruce Richardson <bruce.richardson@intel.com>]

C++ files could not include some headers because "new" is a keyword in
C++, so can't be a variable name

Fixes: 184104fc6121 ("ticketlock: introduce fair ticket based locking")
Cc: stable@dpdk.org

(This is a backport of patch 59144f6edd from mainline)
