Fix bug with -MM -MG.

PR preprocessor/15220
* files.c (_cpp_find_file): New parameter angle_brackets.  Fix all
callers.  Pass to open_file_failed.
(open_file_failed): New parameter angle_brackets.  Fix all callers.
Use in print_dep assignment.
* init.c (cpp_read_main_file): Pass additional arg to _cpp_find_file.
* internal.h (_cpp_find_file): Add new parm to declaration.
