[view compiler] Remove dex_builder_test.cc

Browse Source 
This test is problematic because it links against libdexfile and we would like
to remove this dependency. All of the functionality covered by this test is also
tested more thoroughly by the on-device dex-builder-test, so there's no reason
to test it here as well.
