[PATCH 2/5] abg-leaf-reporter.cc: Fix indentation of function parameter diffs.

[Giuliano Procida <gprocida@google.com>]

When reporting the details of changes to function parameter
differences in leaf-changes-only mode, the details are output at the
same level of indentation as the introductory text. In default mode
the usual 2-space indentation is used.

This patch fixes this discrepancy, making the output more readable.

	* src/abg-leaf-reporter.cc (report): In the fn_parm_diff
	override, indent the lines of detail by 2 spaces.
	* tests/data/test-abidiff-exit/test-leaf3-report.txt: Update
	report with correct indentation.
