openssh: fix potential signed overflow in pointer arithmatic

Pointer arithmatic results in implementation defined signed integer
type, so that 'd - dst’ in strlcat may trigger signed overflow if
pointer ‘d’ is near 0x7fffffff in 32 bits system. In case of ompilation
by gcc or clang with -ftrapv option, the overflow would generate
program abort.
