Add option to radiff to suppress names

The default output is

                       entry0  0x400586 |   MATCH  (0.071429) | 0x400585  entry0
    sym.imp.__libc_start_main  0x4004e0 |   MATCH  (1.000000) | 0x4004e0  sym.imp.__libc_start_main
                 fcn.004004e6  0x4004e6 |   MATCH  (1.000000) | 0x4004e6  fcn.004004e6
              sym.imp.putchar  0x4004c0 |   MATCH  (1.000000) | 0x4004c0  sym.imp.putchar


This new option '-f' changes the output to look like:

    0x0000000000400586 |   MATCH  (0.071429) | 0x0000000000400585
    0x00000000004004e0 |   MATCH  (1.000000) | 0x00000000004004e0
    0x00000000004004e6 |   MATCH  (1.000000) | 0x00000000004004e6
    0x00000000004004c0 |   MATCH  (1.000000) | 0x00000000004004c0

I found this useful for cases where large files with fcn.xxxx just gets in the way
