Fix: local variable hiding parameter of same name

LGTM provides static code analysis and recommendations for code quality
improvements.  Their recent run over the Perl 5 core distribution
identified 12 instances where a local variable hid a parameter of
the same name in an outer scope.  The LGTM rule governing this situation
can be found here:

Per: https://lgtm.com/rules/2156240606/

This patch renames local variables in approximately 8 of those instances
to comply with the LGTM recommendation.  Suggestions for renamed
variables were made by Tony Cook.
