[SFrame-V3] readelf: testsuite: sframe: add new SFrame V2 test

In subsequent commits, we will add support for SFrame V3.  GNU as and ld
will only generate SFrame V3; SFrame V2 will not be supported for
generation.

For readelf/objdump, however, continue to support textual dump of SFrame
V2 sections.  Add a binary file (with no debug data) with SFrame V2
section to keep the dumping tested.

TBD:
 - The cmp file should ideally be a set of regexp checks.
