ld/testsuite: prepare ld-elfvsb to support XCOFF

A following patch will add visibility support in ld for XCOFF. Thus,
ld-elfvsb is renamed ld-vsb and a suffix is added to files targeting only
ELF format.

ld/ChangeLog:

	* testsuite/ld-elfvsb: rename as ld-vsb.
	* testsuite/ld-elfvsb/hidden0.d: move to ld-vsb and rename with
	  suffix -elf.d.
	* testsuite/ld-elfvsb/hidden1.d: Likewise.
	* testsuite/ld-elfvsb/hidden2.d: Likewise.
	* testsuite/ld-elfvsb/internal0.d: Likewise.
	* testsuite/ld-elfvsb/internal1.d: Likewise.
	* testsuite/ld-elfvsb/protected0.d: Likewise.
	* testsuite/ld-elfvsb/protected1.d: Likewise.
