samples: fix binderfs sample 

A routine check for misspelled Kconfig symbols showed on instance
from last year, the correct symbol name is CONFIG_ANDROID_BINDERFS,
not CONFIG_CONFIG_ANDROID_BINDERFS, so the extra prefix must
be removed in the Kconfig file to allow enabling the sample.

As the actual sample fails to build as a kernel module, change the
Makefile enough to get to build as a hostprog instead.
