PATCH: _adb: Just check current dir instead of recursively



So while the previous patch was an improvement in theory, in practice it
seems most android installs don't in fact have 'find'. Or 'printf'. So
this reimplements the remote completion to not do a recursive cached
listing, and just list the current directory instead.
