utf8.c: remove print_spaces()

The previous patch made sure that strbuf_add_wrapped_text() (and thus
strbuf_add_indented_text(), too) always get a strbuf.  Make use of
this fact by adding strbuf_addchars(), a small helper that adds a
char the specified number of times to a strbuf, and use it to replace
print_spaces().
