macOS: replace local strnstr with strcasestr.

bionic, glibc, macOS, and musl all have strcasestr
(see http://man7.org/linux/man-pages/man3/strstr.3.html).

macOS (via BSD) has a strnstr that does what strnstr sounds like it
should do by analogy with strnlen and strncpy.

So we at least need to rename strnstr, but it probably makes more sense
just to switch to strcasestr instead.
