[ARM] Ensure head text is always placed at the start of kernel

Commit 86c0baf1 highlighted that we
may end up with the head text placed elsewhere in the kernel image.
Introduce a new .text.head section to contain the initial kernel
startup code, and always place this section at the beginning of the
kernel image.
