[PATCH, test-suite] Update to RUNSAFELY

[Doug Gilmore]

We found that specifying test-suite RUNUNDER make variable
to be a program plus argument doesn't work.

I attached a patch to fix this issue.

Is it OK if we apply this change?

Thanks,

Doug

Commit comment:

Fix RUNSAFELY make variable definition.

To allow the RUNUNDER script to be run with parameters, the
the definition of RUNSAFELY needs to quote the interpolation
of RUNUNDER.
