[petsc-dev] ignore todays 'master' dashboard.

[Satish Balay]

Looks like our test scripts require all test machines to be up :(

Since one of the boxes is down [ipro] - some of the build scripts
hanged [because ssh to it hanged] - i.e some tests did not run. But
the copy scripts ran and grabbed the old [i.e next] results - and
published on the 'master' dashboard..
