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.

According to Documentation/dev-tools/kunit/style.rst a KUnit test suite
normally should not have "test" in the name. Rename it to follow the
style guide.

Per the reasoning in commit f811f58597ac ("riscv: Replace __ASSEMBLY__
with __ASSEMBLER__ in non-uapi headers"), convert one last remaining
instance of __ASSEMBLY__ in the arch/riscv kprobes code. This entered
the tree from patches that were sent before Thomas' changes; and when
I reviewed the kprobes patches before queuing them, I missed this
instance.

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:).

'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'.
