output_section_statement leak

[Alan Modra]

This frees output_section_statement data, which is currently only used
by elf targets but doing so for all targets is simpler and more
future proof than adding ths to ldelf_finish.  (Doing it there
requires moving the function to ldelfgen.c.)

	* ldemul.c (finish_default): Free os->data.
