iotests: Consistent $IMGOPTS boundary matching
To disallow certain refcount_bits values, some _unsupported_imgopts
invocations look like "refcount_bits=1[^0-9]", i.e. they match an
integer boundary with [^0-9]. This expression does not match the end of
the string, though, so it breaks down when refcount_bits is the last
option (which it tends to be after the rewrite of the check script in
Python).
Those invocations could use \b or \> instead, but those are not
portable. They could use something like \([^0-9]\|$\), but that would
be cumbersome. To make it simple and keep the existing invocations
working, just let _unsupported_imgopts match the regex against $IMGOPTS
plus a trailing space.
