[PATCH 1/2] Remove ABI XML test data file blank lines

[Giuliano Procida]

Following a change which eliminated the output of extra blank lines in
XML output, it now also makes sense to remove such blank lines from
saved generated XML files.

This commit does this.

	* tests/data/test-abidiff/test-PR18166-libtirpc.so.abi: Remove
	blank lines.
	* tests/data/test-diff-dwarf-abixml/PR25409-librte_bus_dpaa.so.20.0.abi:
	Ditto.
	* tests/data/test-diff-dwarf-abixml/test0-pr19026-libvtkIOSQL-6.1.so.1.abi:
	Ditto.
	* tests/data/test-diff-suppr/test45-abi-wl.xml: Ditto.
	* tests/data/test-diff-suppr/test45-abi.xml: Ditto.
	* tests/data/test-diff-suppr/test46-PR25128-base.xml: Ditto.
	* tests/data/test-diff-suppr/test46-PR25128-new.xml: Ditto.
