Fix testsuite failures due to extra errors in strict dialects

Fix testsuite failures due to extra errors in strict dialects

When __STRICT_ANSI__ is defined the incorrect allocators used in these
tests also trigger and additional static assertion. Prune those extra
errors so that the tests don't fail when built with strict dialects.

	* testsuite/23_containers/deque/48101_neg.cc: Prune additional errors
	printed when __STRICT_ANSI__ is defined.
	* testsuite/23_containers/forward_list/48101_neg.cc: Likewise.
	* testsuite/23_containers/list/48101_neg.cc: Likewise.
	* testsuite/23_containers/multiset/48101_neg.cc: Likewise.
	* testsuite/23_containers/set/48101_neg.cc: Likewise.
	* testsuite/23_containers/unordered_multiset/48101_neg.cc: Likewise.
	* testsuite/23_containers/unordered_set/48101_neg.cc: Likewise.
	* testsuite/23_containers/vector/48101_neg.cc: Likewise.
