Android stack tool: Treat /data/data as a synonym for /data/user/0.

The Mojo shell prints messages with paths in "/data/user/0" but the
debugger may print paths with "/data/data".  These paths are
equivalent ("/data/data" is maintained for backwards compatibility)
so make sure the stack tool understands that when it is mapping
symbols.
