[PATCH] MIPS: uapi/asm/ptrace.h: add a missing include

[Aaro Koskinen]

Commit a79ebea62010 (MIPS: ptrace: Fix user pt_regs definition,
use in ptrace_{get, set}regs()) converted struct pt_regs to use __u64.
Some userspace applications (e.g. GDB) include this file directly,
and fail to see this type. Fix by including <linux/types.h>.

The patch fixes the following build failure with GDB 7.8 when using
GLIBC headers created against Linux 3.17:
