kpatch-build: check existance of Makefile.modfinal

Browse Source 
It turns out there is a stretch of time in kernel's history when
CONFIG_DEBUG_INFO_BTF was already added, but Makefile.modfinal wasn't
split off yet. To address those we need to either check the file's
existance or, as @liu-song-6 suggested initially, check config for
CONFIG_DEBUG_INFO_BTF_MODULES=y.
