bfd_get_relocated_section_contents allow NULL data buffer

This patch removes the bfd_malloc in default_indirect_link_order and
bfd_simple_get_relocated_section_contents, pushing the allocation down
to bfd_get_relocated_section_contents.  The idea is to make use of the
allocation done with sanity checking in bfd_get_full_section_contents,
which is called by bfd_generic_get_relocated_section_contents.

Doing this exposed a bug in bfd_get_full_section_contents.  With
relaxation it is possible that an input section rawsize is different
to the section size.  In that case we want to use the larger of
rawsize (the on-disk size for input sections) and size.
