libcxxrt: correct mangled "typeinfo name" symbols in Version.map

libcxxrt: correct mangled "typeinfo name" symbols in Version.map

r260553 added missing C++ typinfos to libcxxrt's version script.
It appears that a number of duplicate mangled symbols were added due to
a cut and paste error. Switch the second instances to _ZTS*,
typeinfo name for *.

Found by lld, which produces an error or warning for duplicate symbols.
