tools/bpf: fix core_reloc.c compilation error

On my local machine, I have the following compilation errors:
=====
  In file included from prog_tests/core_reloc.c:3:0:
  ./progs/core_reloc_types.h:517:46: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘fancy_char_ptr_t’
 typedef const char * const volatile restrict fancy_char_ptr_t;
                                              ^
  ./progs/core_reloc_types.h:527:2: error: unknown type name ‘fancy_char_ptr_t’
    fancy_char_ptr_t d;
    ^
=====

I am using gcc 4.8.5. Later compilers may change their behavior not emitting the
error. Nevertheless, let us fix the issue. "restrict" can be tested
without typedef.
