[PATCH v2 4/7] perf/run: add conf_opts argument to get_var_from_env_or_config()

[Christian Couder]

Let's make it possible to use `git config` type specifiers like
`--int` or `--bool`, so that config values are converted to the
canonical form and easier to use.

This additional argument is now the fourth argument of
get_var_from_env_or_config() instead of the fifth because we
want the default value argument to be unset if it is not
passed, and this is simpler if it is the last argument.
