Subject: [PATCH 4/4] [HACK] kernel-open/Makefile: Remove PAHOLE_VARIABLE

Something in 7.0 broke the quoting in PAHOLE_VARIABLES and caused errors
during BTF generation. Taking a look, this part doesn't really make
sense. It's not supposed to do anything if pahole-flags.sh is present,
but:
1. pahole-flags.sh doesn't exclude c++
2. pahole-flags.sh was replaced with Makefile.btf

Removing this doesn't seem to break the functionality of the module as a
user so until a proper fix from NVIDIA is available, this should be
sufficient.
