[PATCH v3 11/11] kconfig: tests: test if recursive inclusion is detected

[Masahiro Yamada]

If recursive inclusion is detected, it should fail with error
messages.  Test this.

This also tests the line numbers in the error message, fixed by
commit 5ae6fcc4bb82 ("kconfig: fix line number in recursive inclusion
error message").
