[PATCH] printf.3: Return the number of bytes printed, not characters

[Jeremy Baxter]

From https://pubs.opengroup.org/onlinepubs/9699919799/functions/printf.html:

    Upon successful completion, the dprintf(), fprintf(), and printf()
    functions shall return the number of bytes transmitted.

Fixes bug 218600 <https://bugzilla.kernel.org/show_bug.cgi?id=218600>.
