[Buildroot] [git commit] swupdate: fix build without json-c

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=7d8dd2a5d23cfc6d3e71081a09634595837313c2
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

swupdate enables SURICATTA_HAWKBIT by default, which unconditionally selects
JSON. This breaks the build when the optional json-c dependency is not built.
Add a patch fixing SURICATTA_HAWKBIT dependencies.

+Subject: [PATCH] suricata_hawkbit: depends on HAVE_JSON_C
+
+Unconditionally selecting JSON when !HAVE_JSON_C leads to a warning:
+
+warning: (SURICATTA_HAWKBIT) selects JSON which has unmet direct dependencies (HAVE_JSON_C)
+
+and eventually a build failure:
+
+In file included from corelib/artifacts_versions.c:34:0:
+include/parselib.h:61:25: fatal error: json-c/json.h: No such file or directory
+
+Make SURICATTA_HAWKBIT depend on HAVE_JSON_C.
