Android 8.1.0 Release 39 (OPM4.171019.021.Q1)
Add dummy Android.mk to document its absence

The Android.mk provided by the upstream fmtlib repository is for use
with the NDK rather than the platform build, so we have replaced it
with an Android.bp. This change adds back a dummy Android.mk with a
comment documenting this so as to not overly confuse future
maintainers.

Test: None, documentation only
