test: lib/cbprintf_fp: fix test filtering

The commit
6fe9e408 (tests/cbprintf_fp: Filter on CONSOLE_HAS_DRIVER)
added filtering on Kconfig symbol incorrectly - it checked
CONSOLE_HAS_DRIVER instead CONFIG_CONSOLE_HAS_DRIVER so
this test was filtered out (and therefore skipped) on all
platforms.

Fix that.
