[PATCH 02/22] qemuxml2arvtest: Ensure newline at the end of generated .args files

[Peter Krempa <pkrempa@xxxxxxxxxx>]

The switch to internal linebreaking of arguments caused a problem when
generating .args files with VIR_TEST_REGENERATE_OUTPUT as the last
argument isn't terminated with a newline.

Switch to using virCommandToStringBuf and append a newline.
