    Set FSType when constructing FS in luks::get_filesystem_support()
    
    This is functionally identical, but is just to follow established coding
    pattern [1] of specifying the FSType when constructing struct FS, rather
    and setting it afterwards.  luks.cc was added after the aforementioned
    commit, but was being developed in parallel so was created [2] following
    the old coding pattern.

        Initialise all struct FS members

        Add busy detection of LUKS mapping (#760080)
