BazelBuild: Fix exception message when command was interrupted

We used ProcessBuilder#toString() but ProcessBuilder doesn't implement
the toString() method, hence calling toString() would return the
instance identity (e.g. 'java.lang.ProcessBuilder@4488aabb'). Instead
include the command which is more useful.

This issue was detected by ErrorProne.
