native tests are not executable out of the box

[Zygmunt Krynicki]

Tested on JB snowball build.

Native tests are installed to /data/native{test,benchmark,stresstest}

Those directories are inaccessible to the 'shell' user that adb is using. In addition none of the executables are ... executable:

To fix that:

1) chmod 0775 /data/
2) chmod 0755 /data/native*
3) for what in test benchmark stresstest; do find /data/native$what -type f -exec chmod 0755 {} \; done
