build: kernel2minor: work around path length limit
When building for MikroTik devices the kernel2minor tool will sometimes fail with: Can't get lstat from kernel file!: No such file or directory. This is because kernel2minor expects paths no longer than 250 chars. To work around this the include/image-commands.mk has been modified to copy the kernel to a temporary file (/tmp/tmp.XXXXXXXXXX) before calling kernel2minor.
