input: run bpfmt -w -s on all Android.bp files

The bpfmt presubmit lint check has been reporting formatting issues on
some recent CLs, so just make all the suggested formatting fixes in one
CL to get them out of the way.

This CL was made by running the following command:

    $ prebuilts/build-tools/linux-x86/bin/bpfmt -w -s \
          frameworks/native/libs/input/**Android.bp
          frameworks/native/services/inputflinger/**Android.bp

The only manual change was in services/inputflinger/Android.bp, where I
removed the comments from the checkinput target's required list, since
they don't make sense if it's just going to be alphabetically sorted.
