Michal Suchanek 4cc9a2d3b0 bpf_doc: Fix build error with older python versions ...

[ Upstream commit 5fbea42387 ]

The ability to subscript match result as an array is only available
since python 3.6. Existing code in bpf_doc uses the older group()
interface but commit 8a76145a2e adds code using the new interface.

Use the old interface consistently to avoid build error on older
distributions like the below:

+ make -j48 -s -C /dev/shm/kbuild/linux.33946/current ARCH=powerpc HOSTCC=gcc CROSS_COMPILE=powerpc64-suse-linux- clean
TypeError: '_sre.SRE_Match' object is not subscriptable

Fixes: 8a76145a2e ("bpf: explicitly define BPF_FUNC_xxx integer values")
