[PATCH] elf: test: handle different rootsbindir in tst-ldconfig-cache

[Florian Weimer]

* Xi Ruoyao:

> When compiling a glibc for a merged-/usr distro people may set
> rootsbindir=/usr/sbin.  But tst-ldconfig-cache has hard-coded
> /sbin/ldconfig path and so it fails with a different rootsbindir.
>
> Fix it by using support_install_rootsbindir like run_ldconfig in
> test-container.c.
