cuirass: Fix scope mismatch.

Previously STORE would be closed on the first context switch, before
'restart-builds' has completed, leading to an error (writing to a closed
port).

* src/cuirass/base.scm (restart-builds): Remove 'store' parameter.  Wrap
body in 'with-store'.
* bin/cuirass.in (main): Adjust accordingly.
