Make UpdatableSystemFontTest device side test.

As commit 679a824773aee8c4424787e9f36d10de1f984112 removed 'adb shell
stop', this test doesn't need to be a host side test.

This allows us to call FontManager Java API in UpdatableSystemFontTest.
I will rewrite 'cmd font' to FontManager API calls in a following CL.
