libcgroup: upgrade to 2.0

Our UPSTREAM_CHECK_URI was looking at SourceForge, but development has
moved to GitHub so update the URI.

Update to 2.0.

Swap musl-decls-compat.patch for a backport of an upstream commit.

Replace do_install commands with a backport of an upstream commit to
install the PAM module correctly.

Don't mess about installing the library into base_libdir as the /lib vs
/usr/lib prefix split is moot these days.

Delete libcgroupfortesting.so as we don't install the test suite.

-Subject: [PATCH] cgrulesengd: remove umask(0)
-
-One of our partners has noticed that cgred daemon is creating a log file
-(/var/log/cgred) with too wide permissions (0666) and that is seen as
-a security bug because an untrusted user can write to otherwise
-restricted area. CVE-2018-14348 has been assigned to this issue.

-    Remove __.*DECLS nonsense
+From 26f2889113789c176273bd24fcd1592a8064c346 Mon Sep 17 00:00:00 2001
+From: "Anthony G. Basile" <blueness@gentoo.org>
+Date: Tue, 6 Jul 2021 07:54:47 -0600
+Subject: [PATCH 1/2] Replace __BEGIN_DECLS and __END_DECLS with extern "C".
 
-Upstream-Status: Pending
-Signed-off-by: Khem Raj <raj.khem@gmail.com>
+The macros __BEGIN_DECLS and __END_DECLS are a GNU-ism found in
+glibc and uClibc, but not musl.  We replace them by the more general
+extern "C" { ... } block exposed only if we have __cplusplus.
