[Patch AArch64] Include asm/ptrace.h in aarch64-linux-nat.c

[Ramana Radhakrishnan]

Hi,

	A recent change to glibc removed asm/ptrace.h from user.h for AArch64. 
This meant that cross-native builds of gdb using trunk glibc broke 
because aarch64-linux-nat.c because user_hwdebug_state couldn't be found.

Fixed by including asm/ptrace.h like other ports.

Ok ?

regards
Ramana
