libstdc++: Remove redundant -std=gnu++17 option from algorithm tests

GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
dg-options directive prevents running these tests with different modes
such as -std=c++17 or -std=gnu++20.

libstdc++-v3/ChangeLog:

	* testsuite/20_util/function_objects/searchers.cc: Remove
	-std=gnu++17 from dg-options directive.
	* testsuite/20_util/specialized_algorithms/memory_management_tools/1.cc:
	Likewise.

	* testsuite/20_util/specialized_algorithms/uninitialized_value_construct_n/sizes.cc:
	Likewise.
	* testsuite/20_util/unique_ptr/specialized_algorithms/swap_cxx17.cc:
	Likewise.
	* testsuite/25_algorithms/clamp/1.cc: Likewise.
