Remove stale Valgrind reference to mojo_application_manager_unittests.

The target was removed in:
  https://codereview.chromium.org/1091513005
The tests are now part of mojo_shell_unittests.
The valgrind bots don't seem to build or run this target...

TODO: Make Valgrind build and run more mojo tests?

Can you file a bug for running mojo tests on chromium.memory and
chromium.memory.fyi? Right now, we have:

*chromium.memory*
ASAN/LSAN: nothing

*chromium.memory.fyi*
Valgrind: no mojo tests
Dr Memory light: mojo_system, mojo_public_system, mojo_public_utility,
mojo_public_bindings, mojo_public_env, mojo_public_sysperf, mojo_common
Dr Memory full: nothing
TSAN: ipc_mojo_unittests, mojo_common_unittests
