script: do not check for tools upfront in test.bash
script: do not check for tools upfront in test.bash

The test.bash script checks whether the necessary tools are all available and
fails if one or more are not before executing any test.

This prevents the -g, -d, and -x options to be used for passing additional
arguments to the pttc, ptdump, and ptxed tool.

Remove the check.  This still causes tests to fail if one of the tools is not
availble but with a different error message.  If test.bash is called with more
than one test file, there will be one or more error messages per test.
