[PATCH 6.18 034/309] kbuild: install-extmod-build: Package resolve_btfids if necessary

[ Upstream commit 459cb3c054c2352bb321648744b620259a716b60 ]

When CONFIG_DEBUG_INFO_BTF_MODULES is enabled and vmlinux is available,
Makefile.modfinal and gen-btf.sh will try to use resolve_btfids on the
module .ko. install-extmod-build currently does not package
resolve_btfids, so that step fails.

Package resolve_btfids if it may be used.
