sys-libs/compiler-rt-sanitizers: Inline new glibc patches

Inline the patches needed for new glibc (with split tirpc) since they
have not been merged upstream, and are appropriately needed for -9999
as well.

+Subject: [PATCH 7/8] [sanitizer_common] Fix using libtirpc on Linux
+
+Fix using libtirpc on Linux by using pkg-config to detect it, and append
+appropriate include directory.  The libtirpc headers reference one
+another via '#include <rpc/...>', so attempting to include it via
+'#include <tirpc/...>' just failed and resulted in RPC headers not being
+detected at all.
+
+Additionally, perform the header check without -nodefaultlibs as that
+apparently causes it to fail.

+Subject: [PATCH 8/8] [test] Support using libtirpc on Linux
+
+Add compiler flags necessary for using libtirpc on Linux (RPC headers
+split out of glibc).  The flags are obtained via pkg-config.  This fixes
+test failures due to tests being unable to find <rpc/...> includes.
