[OE-core] [PATCH] json-c: Disable icecc to avoid implicit-fallthrough warning as error

[Douglas Royds]

icecc preprocesses source files locally before shipping them off to be compiled
on remote hosts. This preprocessing removes comments, including /* fallthrough */
comments in switch statements that normally prevent the implicit-fallthrough
warning.

Rather than turning off -Werror by patching configure.ac, it is simpler to
disable icecc completely for json-c. There are very few source files to compile,
so the compilation is quick even without icecc.
