libcpp: Fix up -fdirectives-only handling of // comments on last line not terminated with newline [PR100646]
As can be seen on the testcases, before the -fdirectives-only preprocessing
rewrite the preprocessor would assume // comments are terminated by the
end of file even when newline wasn't there, but now we error out.
The following patch restores the previous behavior.

* lex.c (cpp_directive_only_process): Treat end of file as termination
for !is_block comments.
* gcc.dg/cpp/pr100646-1.c: New test.
