ansible: Install gawk for building lttng-modules

While gawk isn't a dependency of lttng-modules, it is now required to
build the Linux kernel when `CONFIG_BUILTIN_MODULE_RANGES` is enabled.

        kbuild: generate offset range data for builtin modules

        Create file module.builtin.ranges that can be used to find where
        built-in modules are located by their addresses. This will be useful for
        tracing tools to find what functions are for various built-in modules.
