user/zfs, user/zfs-utils: update to 0.8.3 and make it build

Update autoconf to remove nonstandard '&>' redirection that causes
module build test to inadvertently background in dash and then fail due
to a race.

Also backport patches to support removal of time_t; commit hashes

+
+    Linux 5.6 compat: time_t
+    
+    As part of the Linux kernel's y2038 changes the time_t type has been
+    fully retired.  Callers are now required to use the time64_t type.
+    
+    Rather than move to the new type, I've removed the few remaining
+    places where a time_t is used in the kernel code.  They've been
+    replaced with a uint64_t which is already how ZFS internally
+    handled these values.
+    
+    Going forward we should work towards updating the remaining user
+    space time_t consumers to the 64-bit interfaces.
