last-modified: fix use of uninitialized memory
git-last-modified(1) uses a scratch bitmap to keep track of paths that
have been changed between commits. To avoid reallocating a bitmap on
each call of process_parent(), the scratch bitmap is kept and reused.
Although, it seems an incorrect length is passed to memset(3).
`struct bitmap` uses `eword_t` to for internal storage. This type is
typedef'd to uint64_t. To fully zero the memory used by the bitmap,
multiply the length (saved in `struct bitmap::word_alloc`) by the size
of `eword_t`.
