Update VERBOSE handling for parallel-tests driver.

* tests/defs.m4sh: Default to verbose output, drop now-unneeded
handling of 'VERBOSE=no'.
* README: Update example usage.
* README.alpha: Likewise.
* doc/libtool.texi (Test descriptions, When tests fail): Remove
unneeded VERBOSE recommendations.  Point to per-test log files
and test-suite.log summary file.
