* Disable color output to avoid appverif problem
There does not appear to be any simple way to use a custom color
class with CATCH2 so we just disable color as is done for a UWP.

* Add libbpf bpf_create_map_in_map() API
* bpf_create_map() now fails for outer maps. You must use
bpf_create_map_in_map() instead.
* Fix bug where EBPF_INVALID_FD was incorrectly converted to
EBPF_INVALID_ARGUMENT by ioctl handling code (part of issue #595)
One symptom of this bug was that errno was being set to EINVAL
in a number of cases which should have been EBADF.
* Fix bug where a HASH_OF_MAPS (unlike ARRAY_OF_MAPS) wasn't enforcing
that an inner map value had to match the inner map template.
Refactored the code in ebpf_maps.c so the checking is in done in one
place called by both maps, to ensure consistency.
* Fix bug in HASH_OF_MAPS where if an update failed, it would leave
the old entry but incorrectly drop the reference it held. It now
preserves the reference since the entry is unchanged.
* Added test case for ARRAY_OF_MAPS created via libbpf. Previously
only HASH_OF_MAPS creation was tested for that path.
