cmumford f8d205cf89 Including atomic_pointer.h in port_posix
A recent CL (104348226) created the port_posix library, but omitted: port/atomic_pointer.h.

And when:

    [] test third_party/leveldb:all

was run this error was reported:

    //third_party/leveldb:port_posix does not depend on a
    module exporting 'third_party/leveldb/port/atomic_pointer.h'
