Revert^2 "Reimplement ojluni JNI_OnLoad from scratch."

This reverts commit 70cd18f61218aa0fa8b7d3ce47b28553fd9ddca1.

The initialization order has been fixed by moving Float,
Double and System to the beginning as they are needed for
resizing StringBuilder's internal buffer, used for class
initializers of some other classes, notably Inet*Addrees.

Also change libbase to be dynamically linked to avoid
multiple definitions of gMinimumLogSeverity which caused
some tests to fail as dalvikvm would initialize a copy in
the libbase.so but JVM_Exit() would use its own copy in
the libopenjdkd.so, ignoring the requested verbosity.

Test: Pixel 2 XL boots.
Test: cts-tradefed run cts --m vm-tests-tf
Test: cts-tradefed run cts -d -m CtsLibcoreTestCases
Test: m test-art-host-gtest
Test: testrunner.py --host --optimizing
Test: Repeat previous 2 tests without preloaded-classes.
