[PATCH 6/7] abidiff: Eliminate leaf mode double blank lines.

[Giuliano Procida <gprocida@google.com>]

In --leaf-changes-only mode, the report currently has 2 blank lines
after each type-diff section. This patches changes this to 1.

	* src/abg-leaf-reporter.cc: (report_diffs) Emit 1 instead of 2
	new lines between sections.
	* tests/data/test-abidiff-exit/test-leaf-peeling-report.txt:
	Replace double blank lines with single ones.
	* tests/data/test-diff-filter/libtest45-basic-type-change-report-1.txt:
	Ditto.
	* tests/data/test-diff-suppr/test36-leaf-report-0.txt: Ditto.
	* tests/data/test-*/test*report*.txt:: Ditto.
