[Buildroot] [git commit branch/2023.02.x] package/haproxy: fix runtime 'FATAL ERROR: invalid code detected -- cannot go further'

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=d3657f363f662c028089c4aeaf6f78f13563c7df
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2023.02.x

Setting HAPROXY_CFLAGS on the haproxy build command line overrides CFLAGS
which were internally set by the haproxy Makefile.

Among those omitted CFLAGS is -fwrapv. Compiling haproxy without it and
and then running the program results in runtime error:

$ haproxy
FATAL ERROR: invalid code detected -- cannot go further, please recompile!
...

To address this issue, include HAPROXY_CFLAGS in the DEFINE variable instead
of CFLAGS in haproxy.mk.
