Android backend: tidy up the --suffix handling.

Android backend: tidy up the --suffix handling.

Make --suffix .foo generate a makefile called GypAndroid.foo.mk,
instead of GypAndroid.mk.foo.

Just a trivial one. I need to use --suffix to handle generating makefiles for
different architectures, and the filenames it was generating were ugly and
didn't trigger make syntax hilighting.

This shall be the last change to this generator that I lgtm without testing
infrastructure in place.

OK. I've been trying the tests locally in an AOSP tree and think I nearly have
it working, so I can look at the gyp bot in the next few days I hope.
