libstdc++: Only add valid -L paths to testsuite linker options
The MacOS linker warns about -L arguments that don't exist, which causes
all tests to fail for the defauly configuration (because libbacktrace
isn't built).
libstdc++-v3/ChangeLog:
* scripts/testsuite_flags.in: Only add src/filesystem/.libs and
src/libbacktrace/.libs to LDFLAGS if those directories exist.
