kconfig: tests: test randconfig for choice in choice
Commit 3b9a19e08960 ("kconfig: loop as long as we changed some symbols
in randconfig") fixed randconfig where a choice contains a sub-choice.
Prior to that commit, the sub-choice values were not set.
I am not sure whether this is an intended feature or just something
people discovered works, but it is used in the real world;
drivers/usb/gadget/legacy/Kconfig is source'd in a choice context,
then creates a sub-choice in it.
For the test case in this commit, there are 3 possible results.
Case 1:
CONFIG_A=y
# CONFIG_B is not set
Case 2:
# CONFIG_A is not set
CONFIG_B=y
CONFIG_C=y
# CONFIG_D is not set
Case 3:
# CONFIG_A is not set
CONFIG_B=y
# CONFIG_C is not set
CONFIG_D=y
CONFIG_E=y
So, this test iterates several times, and checks if the result is
either of the three.
