kernel-headers: adjust PKG_ variables when using git clone method When using an external git clone for the kernel repo, the build would fail because the build won't download [via git] the kernel tarball. This is because the `toolchain/kernel-headers` assumes that the kernel would get downloaded via normal HTTP. The reason for this is the `HostBuild` rule, which calls the `Download/default` rule. To use the `Download/default` we just need to conditionally adjust some PKG_ vars. We can safely use `LINUX_VERSION` as it was already adjusted in the `kernel-version.mk` to avoid collisions with other tarballs.
