libcpp: Fix up handling of block comments in -fdirectives-only mode [PR103130]

Browse Source 
Normal preprocessing, -fdirectives-only preprocessing before the Nathan's

as end of a block comment, but the new -fdirectives-only handling doesn't.

	PR preprocessor/103130
	* lex.c (cpp_directive_only_process): Treat even \*/ as end of block
	comment.
