libstdc++: Make C++17 ignore --disable-libstdcxx-filesystem-ts [PR 94681]
The configure switch should only affect the optional Filesystem TS, not
the std::filesystem features of C++17.
libstdc++-v3/ChangeLog:
PR libstdc++/94681
* acinclude.m4 (GLIBCXX_CHECK_FILESYSTEM_DEPS): Do not depend on
$enable_libstdcxx_filesystem_ts.
* configure: Regenerate.
