collectd: Update to 5.5.1

Update collectd, the backbone of Luci statistics, to 5.5.1

Refresh patches. Main changes:
 - Remove 500-upstream-parallel-build-fix.patch (implemented upstream)
 - Add 600-fix-libmodbus-detection.patch to revert an upstream change
   that broke libmodbus detection in collectd's configure script

+Patch reverts upstream commit:
+https://github.com/collectd/collectd/commit/6124da7a48f28f54fc09ebeb942d1037516fe6ab
+
+The commit changed the detection path due to FreeBSD issues,
+but apparently affects also Openwrt buildroot negatively.
+
+Original explanation:
+  From 6124da7a48f28f54fc09ebeb942d1037516fe6ab Mon Sep 17 00:00:00 2001
+  Subject: [PATCH] Fix libmodbus detection on FreeBSD
+
+  We look for modbus/modbus.h in /usr/local/include/modbus
+  but we should look for modbus.h
+
+  This is only an issue on FreeBSD since /usr/local/include is not
+  in the default search path.
