chroot,whoami: use uintmax_t for printing uids

[Collin Funk]

I noticed these two calls to error assume that uid_t fits in int and
unsigned long int. Attached patch fixes it.

Subject: [PATCH] chroot,whoami: use uintmax_t for printing uids

* src/chroot.c (main): Cast the uid to uintmax_t instead of int.
* src/whoami.c (main): Cast the uid to uintmax_t instead of unsigned
long int.
