Fix annoying bug for payload cached size

[dledda-r7]

This fix a bug for the tool: bundle exec tools/modules/update_payload_cached_sizes.rb

if you have (like me) the MeterpreterDebugBuild set to true in your metasploit configuration, the cachedsize fetched will be the one of meterpreter.<arch>.debug.dll rather than meterpreter.<arch>.dll. this will force to fetch the correct dll binary.

• Ensures that for modules with refname matching meterpreter_, the MeterpreterDebugBuild option is explicitly set to false by default in the options hash.

Verification

do bundle exec tools/modules/update_payload_cached_sizes.rb

with both MeterpreterDebugBuild set to false and true

without this fix, the cached size should change, with the fix it will not.
