pam: return error when PAM info item is unset
pam_fscrypt is crashing with a segfault in copyIntoSecret() when using
Ctrl-C to interrupt a 'sudo' prompt. It is dereferencing a NULL pointer
that is supposed point to the PAM_AUTHTOK item. The problem is that the
Go code assumes pam_get_item() returns a non-success status if the item
is unset, when actually it sets the data pointer to NULL and returns
PAM_SUCCESS.
Fix it by making pam.Handle.GetItem() return an error in that case.
