[PATCH] tools/pygrub: Fix pygrub's --entry flag for python3

[Alejandro Vallejo <alejandro.vallejo@xxxxxxxxx>]

string.atoi() has been deprecated since Python 2.0, has a big scary warning
in the python2.7 docs and is absent from python3 altogether. int() does the
same thing and is compatible with both.

See https://docs.python.org/2/library/string.html#string.atoi:
