builtin/repack: fix leaking line buffer when packing promisors

In `repack_promisor_objects()` we read output from git-pack-objects(1) line by line, using `strbuf_getline_lf()`. We never free the line buffer, causing a memory leak. Plug it. This leak is being hit in t5616, but plugging it alone is not sufficient to make the whole test suite leak free.
