pkg/report: skip atomic functions

For some reason gcc stopped inlining atomic/bitops functions
on a 5.4 kernel (see add test reports).
Skip all atomic/bitops functions from these files:
https://elixir.bootlin.com/linux/latest/source/include/linux/atomic/atomic-instrumented.h
https://elixir.bootlin.com/linux/latest/source/include/asm-generic/bitops/instrumented-atomic.h
