Commit 1017d323cafa ("src: support for selectors with different byteorder with
interval concatenations") was incomplete.
Switch byteorder of singleton values in a set that contains
concatenation of intervals. This singleton value is actually represented
as a range in the kernel.
After this patch, if the set represents a concatenation of intervals:
- EXPR_F_INTERVAL denotes the lhs of the interval.
- EXPR_F_INTERVAL_END denotes the rhs of the interval (this flag was
already used in this way before this patch).
If none of these flags are set on, then the set contains concatenations
of singleton values (no interval flag is set on), in such case, no
byteorder swap is required.
Update tests/shell and tests/py to cover the use-case breakage reported
by Eric.
