[Buildroot] [git commit branch/2022.02.x] package/pkg-generic.mk: only check for virtual package conflicts when building

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=421f58cfa996a27d85b01775521b3c52125de264
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2022.02.x

The configuration checks should only be done when building so that
make allyespackageconfig && make source works.
