Clear *.ini and skin directory on installclean

Currently, skin directory remains across different emulator targets, and
need manual removal.  Also, clear hardware-qemu.ini and config.ini.
(See https://android-review.googlesource.com/94692 for config.ini)

make SignApk do zip alignment

When signing an APK, make the SignApk tool align the stored entries to
(by default) 4-byte boundaries.  This obviates the need to run the
separate zipalign tool, which currently does this job.

The alignment byte count can be specified with the -a option.  OTA
package signing (with -w) never does alignment.

The order of files in the output APK is changed so that all stored
files come first in the output, followed by all non-stored files.
This is not expected to have any impact in practice.

Real "LOCAL_MULTILIB := both" for prebuilts

This uses the fact that unsetting LOCAL_MULTILIB equals "either".
It's useful to build for both 32-bit and 64-bit in the same prebuilt
module definition.
