Ard Biesheuvel 5d17986cbf gcc-plugins/stackleak: Avoid .head.text section ...

commit e7d24c0aa8 upstream.

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.

Fixes: 48204aba80 ("x86/sme: Move early SME kernel encryption handling into .head.text")
