[PATCH] iotests/common.pattern: Quote echos

[Max Reitz]

>From time to time, my shell decides to repace the bracketed numbers here
by the numbers inside (i.e., "=== Clusters to be compressed [1]" is
printed as "=== Clusters to be compressed 1").  That makes tests that
use common.pattern fail.  Prevent that from happening by quoting the
arguments to all echos in common.pattern.
