perf dwarf-aux: Print array type name with "[]"

It's confusing both pointers and arrays are printed as *.  Let's print
array types with [] so that we can identify them easily.  Although it's
interchangable, sometimes it can cause confusion with size like in the
below example.

Note that it is not the same with C syntax where it goes to the variable
names, but we want to have it in the type names (like in Go language).

Before:
  mov [20] 0x68(reg5) -> reg0 type='struct page**' size=0x80 (die:0x4e61d32)

After:
  mov [20] 0x68(reg5) -> reg0 type='struct page*[]' size=0x80 (die:0x4e61d32)
