abitidy: split out unset_attribute functionality
At some point in the past it seemed it might be useful to have a
single function look up and set or unset an attribute value and use an
optional value for uniformity.
However, none of the callers do anything other than construct a new
optional which is then immediately unpacked (if not empty) by the
function.
This change splits set_attribute and unset_attribute into separate
functions and adjusts all callers.
