Always allow agent attach on userdebug builds with kArtTiVersion

We added support for the jvmti-alike ArtTi for use by debuggers on
userdebug/eng builds of android. Extend this support to allow any
agent to be loaded on any process of a userdebug device. These agents
will need to make use of kArtTiVersion (0x70010200) envs.

Test: build
Test: ./test.py --host -j50
Test: ensure AS profiler continues to work with userdebug devices
