sha1_file.c: Don't retain open fds on small packs
If a pack file is small enough that its entire contents fits within one mmap window, mmap the file and then immediately close its file descriptor. This reduces the number of file descriptors that are needed to read from repositories with many tiny pack files, such as one that has received 1000 pushes (and created 1000 small pack files) since its last repack.
