Fix CPAN random tester failures

[fglock]

Summary

• Fix remaining dev/tools/cpan_random_tester.pl failures across the requested CPAN modules.
• Add runtime/interpreter fixes for eval block returns, eval-string captures, regex capture scoping, foreach aliasing, flock, pipe close status, absolute globbing, File::Spec->tmpdir, and %ENV{TZ} localtime handling.
• Add a Module::Pluggable::Ordered distropref patch and focused regression tests for the fixed behavior.

Verification

• make passed (/tmp/make_final_cpan_random.log)
• timeout 600 ./jcpan -t Image::ExifTool passed: 113 files, 600 tests
• timeout 600 ./jcpan -t File::ShareDir::ProjectDistDir passed: 17 files, 21 tests
• timeout 600 ./jcpan -t Sub::Override passed: 1 file, 49 tests
• timeout 600 ./jcpan -t MIDI::Util passed: 8 files, 12 tests
• timeout 600 ./jcpan -t OLE::Storage_Lite passed: 2 files, 199 tests
• timeout 600 ./jcpan -t Module::Pluggable::Ordered passed: 4 files, 11 tests
• timeout 600 ./jcpan -t Email::Date::Format passed: 2 files, 8 tests
• timeout 900 ./jcpan -t Test::Cmd passed: 43 files, 714 tests

Follow-up for the PR854 regression comparison:

• Removed the startup IO::File preload and kept only package-stash seeding, which restores the %INC/startup side effects seen in lib/no_load.t, io/iofile.t, io/open.t, op/caller.t, mro/basic.t, op/runlevel.t, and run/fresh_perl.t.
• Fixed special-variable proxy dereference for $1 symbolic deref cases, restoring uni/variables.t.
• Fixed global destruction traversal for unblessed containers after removing the IO::File preload.
• Re-ran the timeout-looking files single-job with a 360s per-file timeout: io/crlf_through.t and io/through.t pass, while lib/croak.t is back to the parent baseline count.

Verification logs:

• make: /tmp/make_pr854_regression_fixes_2.log PASS
• Focused regression set: /tmp/pr854_regressions_after_fix.log matches parent counts for every non-timeout regression
• Timeout-focused set: /tmp/pr854_timeout_files_after_fix.log
• jcpan -t OLE::Storage_Lite: /tmp/jcpan_ole_storage_lite_after_pr854_regression_fix.log PASS
• jcpan -t Image::ExifTool: /tmp/jcpan_exiftool_after_pr854_regression_fix.log PASS
