Allow tab as a delimiter in smime .index files. (closes #3802)

The old parsing code used fscanf, and so happened to allow a tab as a
delimiter.  Even though smime_keys.pl uses a space, some users
maintain their own .index files by hand (using tab delimiters), so
continue to allow that delimiter.

Thanks to Andre for the bug report and patch.
