tile: support static_key usage in non-module __exit sections
Previously, all the __exit sections were just dropped by the link phase.
However, if there are static_key (jump label) constructs in __exit
sections that are not modules, the link fails with the message:
`.exit.text' referenced in section `__jump_table' of xxx.o:
defined in discarded section `.exit.text' of xxx.o
Support this usage by keeping the .exit.text sections in the final image
if JUMP_LABEL is defined, then discarding them once initialization is
complete.
