Explicitly test command -v host output before trying host command.

We have to explicitly test command -v host worked otherwise on systems
that do not have 'host' installed will return error code 127 and stop
testing. This is because vg_regtest uses '/bin/sh -c' to execute the
prereq command. Found by Petar Jovanovic.
