Michal Rostecki c05a3b69b7 aya-obj: Handle lack of match of enum variants correctly 
When comparing `local_spec` with `target_spec` for enum relocations,
we can encounter a situation when a matchinng variant in a candidate
spec doesn't exist.

Before this change, such case wasn't handled explicitly, therefore
resulted in returning currently constructed `target_spec` at the
end. The problem is that such `target_spec` was, due to lack of
match, incomplete. It didn't contain any `accessors` nor `parts`.

Later usage of such incomplete `target_spec` was leading to panics,
since the code operating on enums' `target_spec` expects at least
one `accessor` to be available.

integration-test: avoid reliance on kernel headers 
This should allow us to build on any system.

integration-test: fix BTF relocation test 
The struct_flavors test previously expected the same thing with and
without relocations. It now expects different values.

Also rename an enum variant "u64" to "S64". This was a typo. Turns out
that U32 is a type that exists in kernel headers, so all enum values are
suffixed with "_VAL".

Remove stdlib.h and the call to exit(). This alone makes the test fail
with a poisoned relocation. Bringing over the map definition makes the
test work again.
Dave Tucker 79ea64ca7f aya: Fix (func|line)_info multiple progs in section 
This commit fixes the (func|line)_info when we have multiple programs in
the same section. The integration test reloc.bpf.c serves as our test
case here. This required filtering down the (func|line)_info to only
that in scope of the current symbol + then adjusting the offets to
appease the kernel.

integration-test: Remove runtime toolchain deps 
Move the use of clang and llvm-objcopy from run-time to build-time. This
allows the integration tests to run on VMs with simpler userlands.

Create a new CI job to build the integration tests separately from
running them. Ship them from that job to the runner job using github
actions artifacts.
