make release: verify-version-*: change comparison logic
verfy-version-debian, verify-version-python and verify-version-components
checked noneqality of the comparison strings and if got "positive"
answer then made that goal fail. But in case of the test ([ ])
execution failed it never got to the 'then' part of the line (and
the 'if [ ... ] then ... fi ' construct doesn't make the script line
fail in case of problems inside [ ].
This commit inverses the "logic", so that only if the comparison for
equality succeeds the script line will exit with 0 and execution
can continue past the failure case to the next line (executed by another
shell) with '@echo done'
