[PATCH] dim: Don't freeze sparse check when there are Kconfig changes

[Arkadiusz Hiler]

If the commit range that is being checked with 'dim sparse' introduces
new Kconfig options 'make' prompts us for our opinion. Since we are
capturing the stdout and -err the user sees nothing and we are seemingly
stuck.

To avoid that and be as non-interactive as possible let's just squeeze
'make olddefconfig' in-between 'git checkout' and the actual 'make'.
