kbuild: Add skip_encoding_btf_enum64 option to pahole
New pahole (version 1.24) generates by default new BTF_KIND_ENUM64 BTF tag,
which is not supported by stable kernel.
As a result the kernel with CONFIG_DEBUG_INFO_BTF option will fail to
compile with following error:
BTFIDS vmlinux
FAILED: load BTF from vmlinux: Invalid argument
New pahole provides --skip_encoding_btf_enum64 option to skip BTF_KIND_ENUM64
generation and produce BTF supported by stable kernel.
Adding this option to scripts/pahole-flags.sh.
This change does not have equivalent commit in linus tree, because linus tree
has support for BTF_KIND_ENUM64 tag, so it does not need to be disabled.
