Convert LeanbackSampleApp's build file from .mk to .bp
LeanbackSampleApp was showing up as a false positive in a local script I
was running while working on b/188652897 (apps that do not have a
manifest file). It is a false positive since the manifest file will be
inside the imported apk
Although b/188652897 is not blocked by this conversion, this will
probably be a necessary change in the future since we will move away
from .mk files
Test: m LeanbackSampleApp # artifacts have same sha
