scripts/gdb: fix dentry_name() lookup

Browse source 
The "d_iname" member was replaced with "d_shortname.string" in the commit
referenced in the Fixes tag.  This prevented the GDB script "lx-mount"
command to properly function:

(gdb) lx-mounts
      mount          super_block     devname pathname fstype options
0xff11000002d21180 0xff11000002d24800 rootfs / rootfs rw 0 0
0xff11000002e18a80 0xff11000003713000 /dev/root / ext4 rw,relatime 0 0
Python Exception <class 'gdb.error'>: There is no member named d_iname.
Error occurred in Python: There is no member named d_iname.
