Subject: makepkg: use c-style for loops for integrity checks

These loops already maintain an independent loop counter, so cut out
the middle man. While this change doesn't necessarily require that we
drop support for sparse arrays, we do via this patch. A new lint check
is added in check_sanity to abort when a sparse array is encountered.
