package/gdb: fix gdbserver build for m68k

As for strace [1], when <sys/reg.h> is included after <linux/ptrace.h>,
the build fails on m68k with the following diagnostics:

In file included from ./../nat/linux-ptrace.h:28:0,
                 from linux-low.h:27,
                 from linux-m68k-low.c:20:
[...]/usr/include/sys/reg.h:26:3: error: expected identifier before numeric constant
   PT_D1 = 0,
   ^
[...]usr/include/sys/reg.h:26:3: error: expected « } » before numeric constant
[...]usr/include/sys/reg.h:26:3: error: expected unqualified-id before numeric constant
In file included from linux-m68k-low.c:27:0:
[...]usr/include/sys/reg.h:99:1: error: expected declaration before « } » token
 };
 ^

Fix this by moving <sys/reg.h> on top of "linux-low.h".
