This fixes tool pygrub to build on x86-64 systems. Currently gcc is
saying there are incompatible pointer type passed into function
ext2fs_file_read. The address of variable n is used in ext2fs_file_read
which takes an "unsigned int *" as the 4th variable. "n" is currently
declared as an "size_t" which is an "int". This declares n as an
"unsigned int" instead of using type "size_t".
