Fix -sysdir handling.

This is a back-port from master to tools_r13

This patch fixes the processing of the -sysdir option. Previously,
using -sysdir <path> would imply that the -system <path>/<path>/system.img
is used, which is incorrect.

Also fixes the skin search for the case where we are using the emulator
without a pre-existing AVD outside of platform builds (e.g. when running tests).

This happens with stuff like:

   emulator -sysdir /path/to/known/sdk/platforms/<name>/images

The patch ensures that the /path/to/known/sdk/platforms/<name>/skins directory
is probed (this was the behaviour of the Tools R11 emulator).
