ucb: webdav-curl: put user name from config into LOCK request

... so that the dialog in SfxMedium::LockOrigFileOnDemand() can show
something more useful than hard-coded URL, which has been used since
commit 99bdd887a6 in 2009 when locking
was added.

This is half of the user info that is put into LO's own lock files
(see svt::LockFileCommon::GenerateOwnEntry()).
