Fix incorrect libstdc++ @headername macro invocation.

[Ollie Wild <aaw at google dot com>]

This patch fixes an incorrect invocation of the @headername Doxygen
macro.  Namely, multiple values must be separated by commas, not "or".
 The effect can be observed at
http://gcc.gnu.org/onlinedocs/gcc-4.7.2/libstdc++/api/a01484.html:

"This is an internal header file, included by other library headers.
Do not attempt to use it directly. Instead, include <map or=""
set>="">."

Submitting as trivial, and will backport to google/gcc-4_7.

Google ref b/7621728.
