Alter the linker section of KUNIT_TABLE to move it out of INIT_DATA and into DATA_DATA.
Data for KUnit tests does not need to be in the init section.
In order to run tests again after boot the KUnit data cannot be labeled as init data as the kernel could write over it.
Add a KUNIT_INIT_TABLE in the next patch for KUnit tests that test init data/functions.

I think this actually fixes a potential bug, as we loop through the list of suites after init has ended in the debugfs logic.
So maybe this is: Fixes: 90a025a859a3 ("vmlinux.lds.h: add linker section for KUnit test suites")
Regardless, I'd love to get this in, even if we don't manage to get the rest of the series in soon.
