[PATCH v4 05/15] gdb: Reliably load modules in runtime_load_module

[Glenn Washburn]

For an unknown reason, GDB has been observed to not hit the grub_dl_add()
software breakpoint in QEMU. When it does, its been observed to stop before
the stack frame is setup causing values of passed arguments to be garbage.
So instead, use a hardware break point on grub_dl_add(), which has not
shown these issues.
