Fix kernel bug in determining whether global subprog's argument is
PTR_TO_CTX,
which is done based on type names. Currently KPROBE programs are broken.
Add few tests validating that KPROBE context can be passed to global
subprog.
For that also refactor test_global_funcs test to use test_loader
framework.

That endless loop+again in the first patch raised my brows a bit.
But I'm assuming they are fine since we are working on a verified
btf_vmlinux at this point...
