[common] Merge duplicated macros in linux-nat.c and linux-low.c

- Subject: [common] Merge duplicated macros in linux-nat.c and linux-low.c
Some ptrace related macros are duplicated in linux-nat.c and
gdbserver/linux-low.c. This patch is to move them together in
common/linux-common.h.
Rebuild gdb and gdbserver on x86-linux successfully. Note that the
dependency tracking in gdbserver is not done in this patch.
