libstdc++: Fix undefined FILE* operations in test
We only need to check that the constructor doesn't clear errno, so
there's no need to use an invalid FILE* for that.
libstdc++-v3/ChangeLog:
PR libstdc++/98001
* testsuite/ext/stdio_filebuf/char/79820.cc: Do not pass invalid
FILE* to constructor.
(cherry picked from commit 2762cb1df686fc1ebcee23c7c4f0f6e8bf5a6abc)
