[PATCH 3/7] Better suppression section parsing delegation.

[Giuliano Procida]

The function read_suppressions hands the same ini config section to
each of four parsing functions, until one succeeds. Each of those in
turn has an early exit if the name of the section doesn't correspond.
This can be simplified.

This patch moves the name checking into read_suppressions so that
exactly one parsing function is called per section.

	* src/abg-suppression.cc (read_suppressions): Call appropriate
	read_foo_suppression function based on section name.
	(read_type_suppression): Remove section name check.
	(read_function_suppression): Ditto.
	(read_variable_suppression): Ditto.
	(read_file_suppression): Ditto.
