lttng-modules: update devupstream to v2.13-rc

To support builds against v5.13+ kernels, bumping the devupstream
to 2.13 and the 2.13-rc series.

Along with the SRCREV update, a port of the existing CONFIG_TRACEPOINTS
patch from the main Makefile to src/Kbuild is done.

The LICENSE file was part of commit [Cleanup: Move headers from toplevel
to include/lttng/], so we adjust the checksum to the new fie contents.

(From OE-Core rev: 18bf7b0eafc5331b0b33c0ae777374e24df741b8)

+Subject: [PATCH] src/Kbuild: change missing CONFIG_TRACEPOINTS to warning
+
+Taken from a previous patch to the main lttng-modules Makefile, by
+Otavio Salvador:
+
+  The lttng-modules are being pulled by the tools-profile image feature,
+  however, not every kernel has the CONFIG_TRACEPOINTS feature enabled.
+
+  This change makes the build do not fail when CONFIG_TRACEPOINTS is not
+  available, allowing it to be kept being pulled by default.
+
+Upstream-Status: Inappropriate [embedded specific]
