psql: Fix psql slash option leaks psql_scan_slash_option() returns a malloc'd string, but \getresults, \gset in pipeline mode, \restrict, and \unrestrict did not free it after consuming or copying the value.
Free these option strings after use. Backpatch to all supported versions. In v17 and older, only \restrict and \unrestrict are affected, so those branches need only that part of the fix.
