Subject: tools/pygrub: Failing to set value to 0 in Grub2ConfigFile

In Grub2ConfigFile the code to handle ${saved_entry} and ${next_entry}
sets arg = "0" but this now does nothing following c/s d1b93ea2615bd
"tools/pygrub: Make pygrub understand default entry in string format"
which replaced arg.strip() with arg_strip in the following line.  This
patch restores the previous behaviour.
