[Buildroot] [PATCH v4 1/2] package/rasdaemon: Add rasdaemon package

[Bastien Curutchet via buildroot <buildroot@buildroot.org>]

Rasdaemon is a tool that aims to replace the edac-tool and provide a way
to collect all hardware error events reported by the Linux kernel in a
common framework.

Add a new package to support rasdaemon in the 'Hardware handling'
section. It depends on libtraceevents to detect the ftrace events
generated by the kernel. There is currently a build issue when sqlite
isn't availaible while it's supposed to be an optional dependency. This
build issue is fixed by patch 0001 (which has been also submitted to the
rasdaemon project itself).

Support for the PCIe AER events is optionnal and implies a dependency on
pciutils so also add a dedicated 'sub-option' to enable it.

Add a SYSV init script to start / stop the daemon

Add myself to the DEVELOPERS file.

+Subject: [PATCH] rasdaemon: fix build when sqlite isn't enabled
+
+Build without SQLite enabled through --enable-sqlite3 still fails if
+sqlite isn't available:
+>   CC       rasdaemon-rasdaemon.o
+> In file included from rasdaemon.c:17:
+> ras-record.h:11:10: fatal error: sqlite3.h: No such file or directory
+>    11 | #include <sqlite3.h>
+>       |          ^~~~~~~~~~~
+> compilation terminated.
+
+Include the sqlite header only if the SQLite feature is enabled.
