5.16.0-RC1: mro/package_aliases_utf8.t failing with PERL_UNICODE=A

Hi,

t/mro/package_aliases_utf8.t is failing for me:

# Failed test 11 - replacing nonexistent nested packages by assigning a glob to a glob updates isa caches (인ንʵ) at ./test.pl line 864
#      got "Cannot decode string with wide characters at ../lib/Encode.pm line 176."
# expected "ok 1\nok 2\nok 3\nok 4"

This happens because the test runs `perl foo.pl $unicode_string` and foo.pl
blindly tries to decode @ARGV as UTF-8. This fails because I've got
PERL_UNICODE=A in my environment (more specifically, PERL_UNICODE=SAL and
LANG=en_US.UTF-8), so @ARGV gets automatically decoded by perl. By the time
foo.pl calls Encode::decode("UTF-8", $ARGV[0]), it's already unicode text.

The solution is probably to set $ENV{PERL_UNICODE} = 0 before shelling out.
