When reading attributes from a file we use fgets(3P) with a buffer size of 2048 bytes. This means that as soon as a line exceeds the buffer size we split it up into multiple parts and parse each of them as a separate pattern line. This is of course not what the user intended, and even worse the behaviour is inconsistent with how we read attributes from the index. Fix this bug by converting the code to use `strbuf_getline()` instead. This will indeed read in the whole line, which may theoretically lead to an out-of-memory situation when the gitattributes file is huge. We're about to reject any gitattributes files larger than 100MB in the next commit though, which makes this less of a concern.
