lttng-modules: backport patches from 2.12.x to fix 5.4.64+ and 5.8.9+ builds

Backporting the 10 patches since the lttng 2.12.2 release. We'll drop
them once .3 is released, but for now, we need the fixes to build
against the latest 5.4, 5.8 and 5.9 kernels.

We also bump the devupstream SRCREV to pickup the same changes.

(From OE-Core rev: 62c87d1a68c4f7c8f30c3c5330dcda9cbcbbbaa7)
