[PATCH v3 02/10] mktag: use default strbuf_read() hint

Change the hardcoded hint of 2^12 to 0. The default strbuf hint is
perfectly fine here, and the only reason we were hardcoding it is
because it survived migration from a pre-strbuf fixed-sized buffer.

See fd17f5b5f77 (Replace all read_fd use with strbuf_read, and get rid
of it., 2007-09-10) for that migration.
