package/zeromq: enable kernel-based feature flags
The current configuration system does not check for cached variables for these flags, and thus they are always disabled when cross-compiling. This patch fixes the configuration system to use cached variables and enables them at configuration time.

+ acinclude.m4: make kernel-specific flags cacheable
+
+ Specifically when cross-compiling, one can be willing to force these
+ variable values using the environment of a config.cache file. This
+ commit makes this possible.
+
+ The affected variables are:
+
+ * libzmq_cv_sock_cloexec
+ * libzmq_cv_so_keepalive
+ * libzmq_cv_tcp_keepcnt
+ * libzmq_cv_tcp_keepidle
+ * libzmq_cv_tcp_keepintvl
+ * libzmq_cv_tcp_keepalive
