VMS' 255-byte limit on %ENV entries messes up Test::Harness' setting
of PERL5LIB, which blows module testing right out of the water. The
following patch removes any @INC entry that has perl_root in it, which
shrinks PERL5LIB down small enough to be OK.
(perl_root, FWIW, is the root of the perl tree on VMS--presumably anything
in there will be automatically in @INC in the child, so we can safely toss
it)
