Subject: vsp-lib: Filter non-filesystem regular characters

Parameters can contain characters not suited to use in filenames.

Add '=','(', and ')' to the filtering, and replace with '_'

This reduces extra escaping, and quoting when working with the output
filenames of failed tests and VSP_KEEP_FRAMES=1
