5fada16057 riscv: tests: Make RISCV_KPROBES_KUNIT tristate
This disallows KUNIT=m and RISCV_KPROBES_KUNIT=y, which produces these
relocs_check.sh warnings when RELOCATABLE=y:

    WARNING: 3 bad relocations
    ffffffff81e24118 R_RISCV_64        kunit_unary_assert_format
    ffffffff81e24a60 R_RISCV_64        kunit_binary_assert_format
    ffffffff81e269d0 R_RISCV_JUMP_SLOT  __kunit_do_failed_assertion

This fixes allmodconfig build.

f2fab61282 riscv: Add kprobes KUnit test
Add KUnit test for riscv kprobes, mostly for simulated instructions. The
test install kprobes into multiple sample functions, and check that these
functions still return the expected magic value.

This test can detect some kprobe bugs reported in the past (in Link:).

cd14b01846 treewide: replace or remove redundant def_bool in Kconfig files
'def_bool X' is a shorthand for 'bool' plus 'default X'.

'def_bool' is redundant where 'bool' is already present, so 'def_bool X'
can be replaced with 'default X', or removed if X is 'n'.
