USER_NOTIF_MAGIC is assigned to int variables in this test so set it to INT_MAX
to avoid warnings:
seccomp_bpf.c: In function ‘user_notification_continue’:
seccomp_bpf.c:3088:26: warning: overflow in implicit constant conversion [-Woverflow]
#define USER_NOTIF_MAGIC 116983961184613L
^
seccomp_bpf.c:3572:15: note: in expansion of macro ‘USER_NOTIF_MAGIC’
resp.error = USER_NOTIF_MAGIC;
^~~~~~~~~~~~~~~~
Fixes: 6a21cc50f0c7 ("seccomp: add a return code to trap to userspace")
