pack-bitmap.c: continue looping when first MIDX bitmap is found
In "open_midx_bitmap()", we do a loop with the MIDX(es) in repo, when the first one has been found, then will break out by a "return" directly. But actually, it's better to continue the loop until we have visited both the MIDX in our repository, as well as any alternates (along with _their_ alternates, recursively). The reason for this is, there may exist more than one MIDX file in a repo. The "multi_pack_index" struct is actually designed as a singly linked list, and if a MIDX file has been already opened successfully, then the other MIDX files will be skipped and left with a warning "ignoring extra bitmap file." to the output.
