nvramtool: fix getopt handling with unsigned char

make failed while executing "OPTION     option_table.h" by printing
nvramtool's usage message when crosscompiling coreboot on the BBB.
The reason is the usage of char for the return value of getopt instead
of int and comparing it to -1 later... although char might be unsigned
as it is usually on ARM.
