luci-app-dockerman: jsmin workaround

jsmin state machine is basic so it fails on this:

return /^https?:\/\//i.test(addr)

interpreting the final // as comment start, not recognizing
it is in a regex. But if we wrap the regex in () then all
is well. jsmin has the comment:

action recognizes a regular expression if it is preceded by the likes of
'(' or ',' or '='.
