libstdc++: Fix test that fails in C++20 mode [PR 99995]
The 17_intro/headers/c++1998/49745.cc test fails for C++20 mode with PCH
enabled, because PCH makes it include <bits/stdc++.h>, which includes
<atomic>, and that includes <unistd.h> in C++20 mode. The <unistd.h>
dependency should go away when C++20 atomic waiting is stable, but will
probably remain while the feature is experimental. Change the test to
always include <bits/stdc++.h>, and XFAIL for C++20 and later.
libstdc++-v3/ChangeLog:
PR libstdc++/99995
* testsuite/17_intro/headers/c++1998/49745.cc: Include all
standard headers and XFAIL for effective-target c++20.
