kconfig: tests: check unneeded "is not set" with unmet dependency 



Commit cb67ab2c ("kconfig: do not write choice values when their
dependency becomes n") fixed a problem where "# CONFIG_... is not set"
for choice values are wrongly written into the .config file when they
are once visible, then become invisible later.

Add a test for this naive case.

Do not write choice values to .config if the dependency is unmet.



"# CONFIG_... is not set" should not be written into the .config file

for symbols with unmet dependency.



This was not working correctly for choice values because choice needs

a bit different symbol computation.



This checks that no unneeded "# COFIG_... is not set" is contained in

the .config file.
