    Fix regression with how Vend::Safe performs initialization
    
    In newer versions of Perl (5.18+) `make test` failed due to some odd interactions with Safe and Unicode
    initialization.  The good news is that the failing routines are no longer needed, because Safe.pm now
    properly sets up Safe compartments with Unicode support without needing our help.
    
    Avoid the special-case handling by Interchange when we are using a new enough Safe.pm.
