Shorten long test names

Long Android.run-test.mk targets cause testing framework to
misbehave. Issues occur in no-prebuild mode when --output-path
parameter generated by the make system is too long. When this
happens oat generation fails silently in oat_file_assistant.cc
during creation of empty vdex and oat files.

Creation fails because file names, which are as long as absolute path
to source dex file, are longer than 255 characters Linux file name
limit.

Because oat generation fails silently affected tests pass even though
they were effectively ran in interpreter mode, instead of intended
default mode.

This CL shortens test names to be at most 35 characters. This helps
make the tests more reliable.
