[Toybox] A couple of minor fixes

[Paul Barker]

Hi all,

I'm in the process of updating to toybox 0.7.1 in OpenEmbedded and I've
made two minor fixes:

* The version should report as 0.7.1 not 0.7.0.

* grep didn't print any output due to printf choking on a field width
  of INT_MAX/2. When trim is not set we can drop the field width
  instead of using a huge default width.

Patches for both issues are attached.

Many thanks,
Paul Barker
