config: also evaluate default unconfigured values in runtime for 'cfg_runtime' settings

Browse Source 
The settings which have their default value evaluated in runtime should
have their 'unconfigured' counterparts also evaluated in runtime since
those values can be constructed by using other settings.

For example, before this patch:

$ lvm dumpconfig --type default --unconfigured devices/cache_dir devices/cache
cache_dir="@DEFAULT_SYS_DIR@/@DEFAULT_CACHE_SUBDIR@"
cache="/etc/lvm/cache/.cache

With this patch applied:

$ lvm dumpconfig --type default --unconfigured devices/cache_dir devices/cache
cache_dir="@DEFAULT_SYS_DIR@/@DEFAULT_CACHE_SUBDIR@"
cache="@DEFAULT_SYS_DIR@/@DEFAULT_CACHE_SUBDIR@/.cache"
