.gdbinit: load QEMU sub-commands when gdb starts

The scripts/qemu-gdb.py file is not easily discoverable. Add a .gdbinit
file so GDB either loads qemu-gdb.py automatically or prints a message
informing the user how to enable them (some systems disable ./.gdbinit
loading for security reasons).

Symlink .gdbinit and the scripts directory in order to make out-of-tree
builds work. The scripts directory is used to find the qemu-gdb.py file
specified by a relative path in .gdbinit.
