gdb: add xtensa fixes for 7.5.1

Two fixes for xtensa are still applicable to gdb-7.5.1, which is now the
default; copy them from 7.4.1. This fixes native gdb build for xtensa.

+Subject: [PATCH] gdb: xtensa: fix linux ptrace includes
+
+Currently, xtensa code using the Linux ptrace interface only include
+sys/ptrace.h.  This file comes from the C library (glibc and uClibc,
+at least), and includes a declaration of the ptrace() functions, along
+with some cross architecture constants that are mostly copied from the
+file located at include/uapi/linux/ptrace.h in recent Linux kernels.
+
+For xtensa specific constants like PTRACE_GETXTREGS and
+PTRACE_SETXTREGS the asm/ptrace.h include from the Linux kernel UAPI
+is needed.  The code in gdbserver xtensa specific part doesn't call
+ptrace() directly, so we can remove the unneeded sys/ptrace.h include.
+The gdb xtensa specific code needs both headers, since it calls
+ptrace().
+
+gdb/
+	* xtensa-linux-nat.c: Include asm/ptrace.h.
+
+gdb/gdbserver/
+	* linux-xtensa-low.c: Include asm/ptrace.h instead of
+	sys/ptrace.h.
