Add pid argument in aarch64_get_debug_reg_state

This patch addes argument pid in aarch64_get_debug_reg_state, so that
its interface is the same on both GDB and GDBserver.

gdb/gdbserver:

	* linux-aarch64-low.c (aarch64_get_debug_reg_state): Add argument pid.
	Find proc_info by find_process_pid.  All callers updated.
