libutils: Remove Static.cpp and darwin hacks.

Bug: N/A
Test: in internal master, the only libraries that reference this
  symbol are:
./prebuilts/sdk/tools/linux/bin/split-select android::gDarwinIsReallyAnnoying
./prebuilts/sdk/tools/linux/bin/aapt android::gDarwinIsReallyAnnoying
./prebuilts/sdk/tools/linux/bin/aapt2 android::gDarwinIsReallyAnnoying
./prebuilts/sdk/tools/linux/lib64/libaapt2_jni.so android::gDarwinIsReallyAnnoying
./prebuilts/sdk/tools/linux/lib64/libaapt2_jni.so android::gDarwinIsReallyAnnoying
+ VNDK libraries
Test: libutils_test
