eal: fix C++ include

[ upstream commit 59144f6 ]

C++ files could not include some headers because:

* "new" is a keyword in C++, so can't be a variable name
* there is no automatic casting to/from void *

Fixes: 184104f ("ticketlock: introduce fair ticket based locking")
Fixes: 032a7e5 ("trace: implement provider payload")
