[Buildroot] [PATCH 1/1] package/mosquitto: fix static build with openssl

[Fabrice Fontaine]

mosquitto library can be built statically since commit
a95bdd964761ec69a23174f5213dd54b77d0971b however build fails with
openssl because mosquitto does not use pkg-config to retrieve static
dependencies so provide them through the STATIC_LIB_DEPS variable

Fixes:
