Subject: [PATCH] xfstests: don't print "do not support" warnings unless verbose is specified

Commit 630421f6d449 attempts to avoid printing the "fallocate not
supported" warning if the -q (quiet) option is specified on the
command-line.  Unfortunately tests 75 and 112 don't set the -q flag.
This causes test failures for file systems that don't support
fallocate or the punch hole functionality.

I considered changing tests 75 and 112 to pass -q to fsx, but that
would suppress other warning messages that could be legitimate test
failures, so I decided to add a new -v (vebose) flag.
