arm64: bti: Fix support for userspace only BTI
When setting PTE_MAYBE_GP we check system_supports_bti() but this is
true for systems where only CONFIG_BTI is set causing us to enable BTI
on some kernel text. Add an extra check for the kernel mode option,
using an ifdef due to line length.
Fixes: c8027285e366 ("arm64: Set GP bit in kernel page tables to enable BTI for the kernel")
