libsepol: remove unused function and type

Browse Source 
Fix the following build warning:
policydb.c: In function ‘get_symtab_destroy_func’:
policydb.c:1581:9: error: cast between incompatible function types from ‘int (*)(char *, void *, void *)’ to ‘void (*)(char *, void *, void *)’ [-Werror=cast-function-type]
  return (hashtab_destroy_func_t) destroy_f[sym_num];
         ^

It turns out that this function and type are long unused in libsepol
and are not exported APIs for the shared library, so just remove them.
