Mark std::list as not relocatable

Summary:
[Folly] Mark `std::list` as not relocatable.

From the github issue (facebook/folly#889), `std::list` allocated storage may hold back-pointers to the owning `std::list` object in both libstdc++ and libc++.

The relocatability marking dates to 2011 or earlier; perhaps it applied then.

Closes #889.
