meson: check string.h not strings.h for explicit_bzero

I used strings.h because that's what explicit_bzero(3) says. But glibc defines
it in string.h. There are no other available implementations atm (musl does not
define it, bionic aliases it to memset in openbsd-compat.h, yikes). We also
include just string.h from the code. So just look for the function in string.h,
and if it ever appears in other places, we can change the detection and includes.
