compiler: Add missing sections to kernel linker script

This caused sporadic LoadFaults with LLD 14 and above, as they
happened to lay out the (not otherwise mentioned) GOT/PLT such
that they would overlap with the stack guard page.

LLD does support the --orphan-handling=error option, which
would be useful to avoid similar problems in the future, but
then we'd need to mention all the other misc sections
(symbol table, comments) in the linker script as well.

GitHub: Fixes #1975.
