Tand the he VFD SWMR test script used `| tee` to redirect test programs'

output, then it tested $? for an error exit.  $? told the error status of
`tee`, though, not the test programs!  So no test failures were counted, even
when some tests clearly failed.  I changed the test script to use a shell
subroutine, `catch_out_err_and_rc`, to catch test programs' output and result
code.
