Use a new libsupport support_bindir_prefix instead of a hardcoded
/usr/bin to create the pldd path on container directory.

Checked on x86_64-linux-gnu with default and non-default --prefix and
--bindir paths, as well with --enable-hardcoded-path-in-tests.

	[BZ #24544]
	* elf/tst-pldd.c (do_test): Use support_bindir_prefix instead of
	pre-defined value.

Thank you for this fix Adhemerval.  I'd like to say that thanks to this
fix the testsuite passes again on my older machine and fixes the problem
which I complained about the other day.  So if anybody (Florian?) wants
to backport the pldd fix to 2.27 *with* the test cases it is possible now.

(Disclaimer: Before changing anything it must be verified that it's really
this patch which fixes the problem and that whether it requires some other
patches.  I have not verified every single commit.)

Regards,

Rafal

The other blocker for the test backport is the lack of the
test-in-container framework.  I'm not sure if we should backport that.

Thanks,
Florian
