[PATCH 1 of 2] libxlu: Rename filename to config_source

[George Dunlap <george.dunlap@eu.citrix.com>]

The "filename" is a bit of a misnomer, as it's only used during error
messages, and in most instances cases is actually set to "command
line".

Rename it to "config_source" to make it clear that it's not used to
actually open any files.

No functional changes.
