libstdc++: Remove accidental -std=gnu++17 from test

This was probably copied from a std::filesystem test and the -std option
wasn't removed.

libstdc++-v3/ChangeLog:

	* testsuite/experimental/filesystem/filesystem_error/cons.cc:
	Remove -std=gnu++17 option.

(cherry picked from commit ed0b4bb29a50d6be0e4b6411b3cc9f22967f1313)
