stdlib.h, arc4random.c: fix arc4random return type to u_int32_t

Change uint32_t to u_int32_t and uint8_t to u_int8_t, removing
completely the dependency on stdint.h.

Based on patch by Timo Teraes <timo.teras@iki.fi>. His comment:
This also fixes a major bug that stdlib.h includes stdint.h. Things
might go very wrong because stdint.h has conditional defines and
if stdlib.h is included before #define's for stdint.h we end up
missing things and breaking builds (e.g. openjdk).
