libstdc++: Remove <sstream> dependency from std::bitset::to_ulong() test

There's no need to use a stringstream to test the to_ulong() member.
This will allow the test to be used in freestanding mode.

libstdc++-v3/ChangeLog:

	* testsuite/20_util/bitset/access/to_ulong.cc: Construct bitset
	from binary literal instead of using stringstream.
