Set __rlimit_resource_t definition for all uclibc (c_ulong).

Bring all linux RLIMIT definitions into arch/generic/mod.rs or respective architectures.
Define all RLIMIT constants for all architectures.
Move BLKSSZGET/BLKPBSZGET with their other Ioctls Constants.
arch/generic/mod.rs No need to check for mips(64), powerpc(64), or sparc(64).
