elf: Also try DT_RUNPATH for LD_AUDIT dlopen [BZ #28455]
DT_RUNPATH is only used to find the immediate dependencies of the
executable or shared object containing the DT_RUNPATH entry. Update
LD_AUDIT dlopen call to try the DT_RUNPATH entry of the executable.
Add tst-audit14a, which is copied from tst-audit14, to DT_RUNPATH and
build tst-audit14 with -Wl,--disable-new-dtags to test DT_RPATH.
This partially fixes BZ #28455.

Rewrite test inclusion to use older stdout pattern.
