libstdc++, testsuite, Darwin: Prune a new linker warning present form XCode 16.

Browse source 
Darwin's linker now warns when duplicate rpaths are presented - which
happens when we emit duplicate '-B' paths.  In principle, we should avoid
this in the test-suite, however at present we tend to have duplicates
because different parts of the machinery add them.  At some point, it might
be nice to have an "add_option_if_missing" and apply that across the whole
of the test infra. However this is not something for late in stage 4.  So
the solution here is to prune the warning - the effect of the duplicate in
the libstdc++ testsuite is not important; it will make the exes very slightly
larger but it won't alter the paths that are presented for loading the
runtimes.

libstdc++-v3/ChangeLog:

	* testsuite/lib/prune.exp: Prune ld warning about duplicatei
	rpaths.
