package/fluent-bit: bump to 3.2.0

News:

https://fluentbit.io/announcements/v3.2.0/
https://fluentbit.io/announcements/v3.1.10/
https://fluentbit.io/announcements/v3.1.9/
https://fluentbit.io/announcements/v3.1.8/
https://fluentbit.io/announcements/v3.1.7/
https://fluentbit.io/announcements/v3.1.6/
https://fluentbit.io/announcements/v3.1.5/
https://fluentbit.io/announcements/v3.1.4/

Support has been added for (some) system provided libraries,
see:
 - fluent/fluent-bit#7286
 - fluent/fluent-bit#8930

The c-ares and nghttp2 package are always needed, so use
the buildroot shipped versions. Also allow the usage of
libbacktrace and jemalloc.

A bunch of new compile fixes have been added,
all of them are proposed upstream for review.

+Fluent-bit is c only, so no need to compile cxx.
+This fixes also a compile error in buildroot.
