config: implement --fixed-value with --get*

Browse source 
The config builtin does its own regex matching of values for the --get,
--get-all, and --get-regexp modes. Plumb the existing 'flags' parameter
to the get_value() method so we can initialize the value-pattern argument
as a fixed string instead of a regex pattern.
