kernel distgit changes

I would like to get Fedora/RISCV [0] kernel distgit changes merged. The changes have not changed in significant way for several kernel releases now. The built upstream kernel (a single image) works on QEMU virt machine and SiFive Unleashed board (physical RV64GC hardware).

Configuration wise there are two generic changes (touched other arches):

  configs/fedora/generic/CONFIG_ARM_TIMER_SP804
  configs/fedora/generic/CONFIG_NETFILTER_XT_TARGET_MASQUERADE

- We disable CONFIG_ARM_TIMER_SP804 for all arches expect ARM and ARM64. For some reason Kconfig constantly attempts to select it while building kernel for riscv. This should have no actual affect.

I also upstreamed a patch to add COMPILE_TEST: https://github.com/torvalds/linux/commit/dfc82faad72520769ca146f857e65c23632eed5a

- CONFIG_NETFILTER_XT_TARGET_MASQUERADE seems to be the only target not built from CONFIG_NETFILTER_XT_TARGET_* set thus I added it. This should have no actual affect as all arches already have "CONFIG_NETFILTER_XT_TARGET_MASQUERADE=m" in their configs thus it's auto-selected by Kconfig.
