gcc-plugins/stackleak: Avoid .head.text section

The .head.text section carries the startup code that runs with the MMU off or with a translation of memory that deviates from the ordinary one. So avoid instrumentation with the stackleak plugin, which already avoids .init.text and .noinstr.text entirely.
