Subject: Tests fail when no '.' in @INC ( Can't locate t/08-redirect.pl in @INC )

I observe you have existing attempts at fixing tests for this, but alas, it wasn't enough.

Unfortunately, 'require "t/foo.pl" '  *also* triggers @INC traversal.

The only way to subvert @INC lookup is to either

a: Use a fully qualified path

b: Use a path with a leading "./"

Both of these are special cased.

Compare the results of running the tests directly vs with "legacy compat mode" enabled.

 PERL_USE_UNSAFE_INC=1 perl -Mblib=blib t/11-redirect-oo.t
ok 1 - Redirection with OO
1..1

 The attached patch as proof of concept should fix t/08-redirect.t , but 11-redirect-oo.t still needs its own fix.

Please make sure to run

PERL_USE_UNSAFE_INC=0 make test

on Perl 5.25.11+ when done to defeat TAP::Harness auto-magically hiding failures ( it internally sets PERL_UNSAFE_INC=1 if its not set )
