lib: enforce consistent `index()` behavior with empty needle argument
On macOS, the `memmem()` function returns `NULL` instead of the expected
start of the haystack string when given a zero-length needle argument.
Add special case handling for a zero-length needle argument to ensure
that the expected offset `0` is returned on all systems.
