libstdc++: Use dg-require-filesystem-ts in link test

This test expects to be able to link, which fails if there are undefined
references to chdir, mkdir etc. in fs_ops.o in the libstdc++.a archive.

libstdc++-v3/ChangeLog:

	* testsuite/27_io/filesystem/path/108636.cc: Add dg-require for
	filesystem support.

(cherry picked from commit c07d82c12f2f17427a89188abad69af195590309)
