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.
