I don't think you can do this without a custom JQL function. Normally I would be suggesting writing your own with ScriptRunner, but there is a small bug that prevents using relational operators with custom functions. I've fixed it, but won't be released for a couple of weeks. 

If you want to write your own see https://developer.atlassian.com/jiradev/jira-platform/building-jira-add-ons/jira-plugins2-overview/jira-plugin-module-types/jql-function-plugin-module, the important stuff for getting the last Friday of every month is in the getValues method. Code is at https://gist.github.com/jechlin/25557469af8b8013f62c6e4d3852be27.

So to get stuff resolved in the previous month you would use:

resolutiondate > endOfBusinessMonth(-2) and resolutionDate <= endOfBusinessMonth(-1)

Thanks very much Jamie, I'll save this in my script root and will wait for the SR update you mentioned to trial it...
