tests: Move qemu caps XML parsing into shared unit

Browse Source 
Later on, we the qemu capabilities XML parsing code may come handy so
instead of duplicating the code make the already existing one shared.
By the same time, make the function accept file name instead of XML
document stored already in memory.
