[LTP] [PATCH 1/2] regen.sh: Use intptr_t for tst_syscall return

Some syscalls directly return pointers, like brk or mmap. int is currently
used for the return value in tst_syscall but is not large enough
to guarantee that such a returned value will fit.
Instead, use intptr_t which is guaranted to be castable to (void *)
without loss of data.
