readelf: improve output format for .gcc_except_table

Before the change:
```
 Call site table: [   0] Call site start:   0x10
        Call site length:  12
        Landing pad:       0x2a
        Action:            3
 [   1] Call site start:   0x1c
        Call site length:  123
        Landing pad:       0
        Action:            0

 Action table: [   0] ar_filter:   1
        ar_disp:     0
 [   1] ar_filter:   2
        ar_disp:    -3    -> [   0]
```

After:
```
 Call site table:
 [   0] Call site start:   0x10
        Call site length:  12
        Landing pad:       0x2a
        Action:            3
 [   1] Call site start:   0x1c
        Call site length:  123
        Landing pad:       0
        Action:            0

 Action table:
 [   0] ar_filter:   1
        ar_disp:     0
 [   1] ar_filter:   2
        ar_disp:    -3    -> [   0]
```
