ART: Modify build.sh in order to make it compatible with DaCapo benchmarks

This change makes it possible to run DaCapo benchmarks as part
of our benchmarking framework. It consists of three parts:
1. Making it possible to allocate more memory for dx tool by
with _JAVA_OPTIONS environment variable.
2. Using --min-sdk-version=26 to fix compilation errors of
DaCapo benchmarks.
3. Using --multi-dex to avoid 64K limit on number of method
references

Test: ./scripts/benchmarks/benchmarks_run_target.sh AvroraBench
--iterations 2 --mode 64 --skip-build
./benchmarks/test/test.py
