FreeBSD: Fix format of vfs.zfs.arc_no_grow_shift

Browse Source 
vfs.zfs.arc_no_grow_shift has an invalid type (15) and this causes
py-sysctl to format it as a bytearray when it should be an integer.

"U" is not a valid format, it should be "I" and the type should match
the variable type, int.  We can return EINVAL if the value is set below
zero.
