lib: Redirect to tst_brk_() early
This is first patch of a patchset that would allow us to use SAFE_MACROS() in
newlib testcases. After the patch we redirect to tst_brk_() in case of newlib
tests directly in the test library code.
This is needed since the tst_brkm_() from the old library is marked as
attribute ((noreturn)) and because of that the return address is not
saved on stack and hence we cannot return from the function. Removing
the atrribute is not an option either since that generates ~1000
"control reaches end of non-void function" warnings.
This commit redefines tst_brkm in test.h for the test library code so that we
branch depending on if we are running oldlib/newlib testcase and call
corresponding tst_brk_() or tst_brkm_() function directly instead of branching
in the tst_brkm_() code.
We also had to add a few returns to various places in the test library so that
we exit corresponding function in a case that tst_brkm() actually returned.

tst_virt: Make use of systemd-detect-virt if available
The problem is that there is no defined way to detect if we are inside
of a virtual machine, only bunch of heuristics. If you look at the
src/basic/virt.c in systemd source code it's ~500 lines of code that
tries many different things to try to guess if we are running
virtualized and under what hypervisor.
Currenlty LTP fails to detect KVM in OpenStack Cloud (and possibly many
more) since the /proc/cpuinfo does not contain the QEMU string there.
You can also boot QEMU with non-default -cpu option and you will get the
same result.
The easiest solution is to try the systemd-detect-virt first if it
exists, then we fall back to the previously implemented detections for
older distributions. This is not complete solution, as the detection
still fails with older and non-systemd distributions, but it at least
fixes the bug for most distributions.

lib: safe_stdio.c, tst_virt.c: delete the redundant code
Since tst_brkm() can break remaining test cases, the code
after this function is redundant.

getrusage04: skip it on Xen
Skip this test on Xen, as it is known to fail, presumably because
Xen is not able to account virtual CPU time with same accuracy
as on the real CPU.

lib: add tst_is_virt()
The initial version supports only generic check for xen dom0/domU,
but should allow to easily extend it for other types of checks,
(e.g. KVM guest) if needed later.
